PR #5072 followed by #5406 tweaked the handling of the associative
array 'aliashash' when in zsh. However, upon further investigation
the root of the problem was the 'aliashash' was not being declared
properly as it was declared within a method and therefore not
accessible to the rest of the completion script.
The previous commit of this PR makes the necessary change to properly
declare 'aliashash' which makes the previous tweak unecessary. This
commit removes the tweak.

This is a bug I ran into when working on Helm completion.
I was surprised that it didn't happen when I was using
kubectl, so I investigated and found a PR that fixed this
bug in kubectl:
https://github.com/kubernetes/kubernetes/pull/48553
I duplicated the code in this commit which:
Removes __helm_declare, which is safe to do since
`declare -F` is already replaced to `whence -w` by
__helm_convert_bash_to_zsh().
The problem was that calling "declare" from inside a function
scopes the declaration to that function only. So "declare"
should not be called through __helm_declare() but instead
directly.
To reproduce:
1- setup helm completion in zsh
2- helm --kubeconfig=$HOME/.kube/config statu<TAB>
you will get the error:
__helm_handle_flag:27: bad math expression: operand expected at end of string

This commits adds the possibility to back Tiller (or the future
Tiller-less Helm CLI) with any SQL database (only postgres has been
tested so far) to store release information.
The main motivation for this commit was to use a storage backend that
would allow releases larger that 1MB in size (ConfigMap or Secret
drivers don't, because of limits on value size in the underlying etcd
key-value store).

Flags sometimes can be used with an = sign, such as --kube-context=prod.
In this case, the variable ${flagname} retains the = sign as part of the
flag name. However, in zsh completion, an = sign cannot be part of an
index of the associative array 'flaghash' or else it causes an error.
This commits strips the = sign out when using ${flagname} as an index.
Note that this is not a big deal since flaghash is not actually used
anywhere in Helm completion. I believe it is made available by the
Cobra framework in case some completions choose to use it.

This adds the `--probe=[true|false]` flag to `tiller`, so that you can selectively disable the following probing HTTP endpoints:
- `/readiness`
- `/liveness`
- `/metrics`
One of expected use-cases of this feature would be to avoid consuming an extra port per `tiller`, which becomes more problematic in the [tillerless](https://github.com/rimusz/helm-tiller) setup.
The default is `--probe=true`, which starts the probing endpoints as before.
Implementation-wise, I intentionally made it so that the number of changed lines is as small as possible.
That is, I opted not to factor out the probes server starting logic into its own function, like `startProbesServer`.
Instead, I just added conditionals to the logging part and the server starting part.
As it isn't easily E2E testable, I've verified it to work by running the following commands manually.
With probing enabled(default):
```
$ ./tiller
[main] 2019/04/06 09:20:15 Starting Tiller v2.12+unreleased (tls=false)
[main] 2019/04/06 09:20:15 GRPC listening on :44134
[main] 2019/04/06 09:20:15 Probes listening on :44135
[main] 2019/04/06 09:20:15 Storage driver is ConfigMap
[main] 2019/04/06 09:20:15 Max history per release is 0
```
With probing disabled, you'll see no tiller is no longer listening on 44135:
```
$ ./tiller --probe=false
[main] 2019/04/06 09:20:07 Starting Tiller v2.12+unreleased (tls=false)
[main] 2019/04/06 09:20:07 GRPC listening on :44134
[main] 2019/04/06 09:20:07 Storage driver is ConfigMap
[main] 2019/04/06 09:20:07 Max history per release is 0
```
To ensure that tiller can disable the probing endpoints, I ran multiple tillers at once, with/without `--probe=false`:
The first test runs three tillers without `--probe=false`.
As expected, it results in two tillers failes due to the conflicting port, as you can see in the message `Probes server died: listen tcp :44135: bind: address already in use`.
```
$ bash -c 'for i in {0..2}; do (./tiller --listen=:$((44136+$i)) 2>&1 | sed "s/^/tiller $i: /" )& done; sleep 3 ; pkill tiller'
tiller 1: [main] 2019/04/06 09:57:49 Starting Tiller v2.12+unreleased (tls=false)
tiller 1: [main] 2019/04/06 09:57:49 GRPC listening on :44137
tiller 1: [main] 2019/04/06 09:57:49 Probes listening on :44135
tiller 1: [main] 2019/04/06 09:57:49 Storage driver is ConfigMap
tiller 1: [main] 2019/04/06 09:57:49 Max history per release is 0
tiller 0: [main] 2019/04/06 09:57:49 Starting Tiller v2.12+unreleased (tls=false)
tiller 0: [main] 2019/04/06 09:57:49 GRPC listening on :44136
tiller 0: [main] 2019/04/06 09:57:49 Probes listening on :44135
tiller 0: [main] 2019/04/06 09:57:49 Storage driver is ConfigMap
tiller 0: [main] 2019/04/06 09:57:49 Max history per release is 0
tiller 0: [main] 2019/04/06 09:57:49 Probes server died: listen tcp :44135: bind: address already in use
tiller 2: [main] 2019/04/06 09:57:49 Starting Tiller v2.12+unreleased (tls=false)
tiller 2: [main] 2019/04/06 09:57:49 GRPC listening on :44138
tiller 2: [main] 2019/04/06 09:57:49 Probes listening on :44135
tiller 2: [main] 2019/04/06 09:57:49 Storage driver is ConfigMap
tiller 2: [main] 2019/04/06 09:57:49 Max history per release is 0
tiller 2: [main] 2019/04/06 09:57:49 Probes server died: listen tcp :44135: bind: address already in use
```
The second test runs three tillers with `--probe=false`.
It results in all tillers running without errors, that indicates this feature is working as expected:
```
$ bash -c 'for i in {0..2}; do (./tiller --listen=:$((44136+$i)) --probe=false 2>&1 | sed "s/^/tiller $i: /" )& done; sleep 3 ; pkill tiller'
tiller 1: [main] 2019/04/06 09:58:18 Starting Tiller v2.12+unreleased (tls=false)
tiller 1: [main] 2019/04/06 09:58:18 GRPC listening on :44137
tiller 1: [main] 2019/04/06 09:58:18 Storage driver is ConfigMap
tiller 1: [main] 2019/04/06 09:58:18 Max history per release is 0

As many people have requested and discussed in #3159.
The variable name are kept the same as before. Corresponding command-line flag is named, and description are written, after the existing flag for gRPC.
The scope of this change is intentionally limited to the minimum. That is, I have not yet added `--probe=false`, because it shouldn't be a blocker if we can change the port number.

This is the fix for only one particular, but important case.
The case when a new resource has been added to the chart and
there is an error in the chart, which leads to release failure.
In this case after first failed release upgrade new resource will be
created in the cluster. On the next release upgrade there will be the error:
`no RESOURCE with the name NAME found` for this newly created resource
from the previous release upgrade.
The root of this problem is in the side effect of the first release process,
Release invariant says: if resouce exists in the kubernetes cluster, then
it should exist in the release storage. But this invariant has been broken
by helm itself -- because helm created new resources as side effect and not
adopted them into release storage.
To maintain release invariant for such case during release upgrade operation
all newly *successfully* created resources will be deleted in the case
of an error in the subsequent resources update.
This behaviour will be enabled only when `--cleanup-on-fail` option used
for `helm upgrade` or `helm rollback`.

Normally zsh arrays start at index 1 but when emulating other shells
this may change. During completion, we run the command
emulate -L sh
which affects the indexing of zsh arrays to make it start at 0.
Consequently, when replacing FUNCNAME by funcstack, we should not
change the index.

Cobra provides some out-of-the-box debugging for bash completion.
To use it, one must set the variable BASH_COMP_DEBUG_FILE to
some file where the debug output will be written. Many of the
debug printouts indicate the current method name; they do so
by using bash's ${FUNCNAME[0]} variable. This variable is
different in zsh. To obtain the current method name in zsh
we must use ${funcstack[1]}.
This commit adds the proper sed modification to convert from
bash to zsh.

The lint command cannot parse a compressed chart with a pre-release
version, e.g. 0.1.0-alhpa: it errors out saying it cannot find the
Chart.yaml file. This is due to the way the lint command identifies the
chart dir name, i.e. using the last hyphen in the name of the compressed
file. Changing this method to using the name of the single directory
with the chart's name, as expected from decompressing a chart, allows
lint to parse pre-release charts.
