This is part of HIP 20 which provides a means to have v3 charts
that live alongside v2 charts while having breaking changes.
The plan is to have a different release object for v3 chart
instances for at least a couple reasons:
1. So that the chart object on the release can be fundamentally
different.
2. So that Helm v3 does not detect or try to work with instances
of charts whose apiVersion it does not know about.
Note: it is expected that Helm v3 usage will be used long after
the Helm project no longer supports it. 5 years after Helm v2
had reached end-of-life there was still usage of it.
Note: The release util package is separate from the versioned
elements as it is planned to use generics to handle multiple
release object versions.

This change moves the code, updates the import locations, and
adds a doc.go file to document what the v2 package is for.

The releaseutil package was originally designed to work against a
generated codebase from a protobuf in Helm v2. This is when Helm
used gRPC to communicate to a server side component named Tiller.
When Helm moved everything client side, this package remained and
it supported the release package.
This change moves releaseutil to be a sub-packge of release. This
is part of the change to support apiVersion v3 charts which is
documented in HIP 20

chartutil was originally created to operate on protobufs which are
no longer part of Helm. The util package makes more sense to be
part of the chart package.
This change is part of the HIP 20 to create v3 charts and
explicitly call out v2 charts. The changes for this are in smaller
bite size changes.

Since Helm is going through breaking changes with Helm v4, the version path to
Helm needs to be updated.

This change adds a new flag to the install and upgrade commands in
the Helm client and properties to the install and upgrade action.
The new flag is --hide-secret and can only be used with the
--dry-run flag.
The --dry-run flag is designed to send all chart rendered manifests to
stdout so that they can be inspected.
When the --hide-secret flag is used the Secret content is removed from
the output.

When a helm command is run with the --dry-run flag, it will try to connect to the cluster
if the value is 'server' to be able to render lookup functions.

When #8156 was merged it had the side effect that all hooks were
run all the time. All the hooks were put in the flow of the
content rendered and sent to Kubernetes on every command.
For example, if you ran the following 2 commands the test hooks
would run:
helm create foo
helm install foo ./foo
This should not run any hooks. But, the generated test hook is run.
The change in this commit moves the writing of the hooks to output
or disk back into the template command rather than in a private
function within the actions. This is where it was for v3.2.
One side effect is that post renderers will not work on hooks. This
was the case in v3.2. Since this bug is blocking the release of v3.3.0
it is being rolled back. A refactor effort is underway for this section
of code. post renderer for hooks should be added back as part of that
work. Since post renderer hooks did not make it into a release it
is ok to roll it back for now.
There is code in the cmd/helm package that has been duplicated from
pkg/action. This is a temporary measure to fix the immediate bug
with plans to correct the situation as part of a refactor
of renderResources.

If two `helm upgrade`s are executed at the exact same time, then one of
the invocations will fail with "already exists".
If one `helm upgrade` is executed and a second one is started while the
first is in `pending-upgrade`, then the second invocation will create a
new release. Effectively, two helm invocations will simultaneously
change the state of Kubernetes resources -- which is scary -- then two
releases will be in `deployed` state -- which can cause other issues.
This commit fixes the corrupted storage problem, by introducting a poor
person's lock. If the last release is in a pending state, then helm will
abort. If the last release is in a pending state, due to a previously
killed helm, then the user is expected to do `helm rollback`.
