This commit replaces `ensure.TempDir` with `t.TempDir` in tests. The
directory created by `t.TempDir` is automatically removed when the test
and all its subtests complete.
Prior to this commit, temporary directory created using `ensure.TempDir`
needs to be removed manually by calling `os.RemoveAll`, which is omitted
in some tests. The error handling boilerplate e.g.
defer func() {
if err := os.RemoveAll(dir); err != nil {
t.Fatal(err)
}
}
is also tedious, but `t.TempDir` handles this for us nicely.

This adds support for generating the repository index file in JSON
format using the `--json` flag. The index itself is still written
to `index.yaml`, which is fully backwards compatible as YAML is a
superset of JSON.
For big indexes (think multiple megabytes), this approach is however
more efficient in combination with the changes to the load logic,
as it prevents a YAML -> JSON roundtrip during decoding.

When an index is in a JSON format, the `sigs.k8s.io/yaml` package uses
an inefficient approach to unmarshaling the data, as it does an
unnecessary roundtrip on the data to transform the YAML to valid JSON.
To prevent this from happening, detect if the bytes which we attempt
to load contain valid JSON, and unmarshal them directly using
`json.Unmarshal` instead.

There are a few changes to the new dry-run handling:
1. Some documentation is added to help clarify what is happening
and what is expected.
2. DryRun is never changed by internal handling. If an API user
sets the property it is not changed by our code.
3. The behavior on contacting the server with false/none is made
consistent between install and upgrade.

Some charts don't need a templates directory. The warning appears to originate back when helm expected all charts to contain templates. In CI situations where linting is performed with --strict the lint warning causes unneccessary failures for charts that quite legitimately do not contain a templates directory.
As discussed in #8033 there are no longer any scenarios understood where this warning is helpful so this commit removes it.

First, some notes about priority and how some code flow works.
For Helm handling values, the expected order of precidence is:
1. User specified values (e.g CLI)
2. Imported values
3. Parent chart values
4. Subchart values
Helm handles dependency values slightly differently. If there are dependencies
in the charts folder that are not marked as dependencies all of the values,
including nil values, are pulled in. If those charts are listed as a
dependency in the Chart.yaml file than they are processed for import handling.
Prior to the changes here, it caused nil values at the top level to NOT remove
values specified.
The changes:
1. The order of priority was chagned from the list above. Parnet chart values
would override specifically imported values. This is due to a change from
just over a year ago that introduced a bug. That was undone by changing the
precidence when maps were merged.
2. To handle merging while retaining the nil values, which was causing
inconsistent behavior, a new set of Merge functions were introduced. These
functions are just like coalesce except that they DO NOT remove nil/null values.
The new functions are used in a backward compatible manner meaning some new
functions were introduced that called them.
Specific issues fixed (that are known):
Closes#9027
Can now delete subkeys from charts when specified in the parent. This behavior
was previously inconsistent. Sometimes they could be deleted and other times
it did not work. Now it is consistent.
Closes#10899
Imported values (from library or other subcharts) are now used following the
order above.
The previous behavior was inconsistent. import-values using just a string
would import them. When named with a child/parent it did not work if the
parent already had a value. If string and named were mixed the imports
worked if the string happened first but just for the string not the named.
If the named parent/child went first then none of them worked for cases
where the parent already had a value. It was inconsistent and the tests
sometimes mirrored the functionality rather than expected behavior.
Tests for this fall into the sub-packages and are in the template tests
to verify it's happening in the output. Including having values passed
at the CLI as the ultimate highest priority to be used.
This relates to a fix that went in for #9940. The expected values there don't
fit the precedence above where the parent value would override the imported
value. That fix/change introduced more bugs.
Closes#10052
This is the case where imported values using the parent/child designation
just didn't work right. That has been fixed and there are tests. The underlying
issue had to do with the precedence order handling.
Note, a lot of tests were added. Hope we got it more right this time.

Add a new flag `--plain-http` to the following commands:
* `helm install`
* `helm pull`
* `helm push`
* `helm template`
* `helm upgrade`
* `helm show`
This flag instructs the registry client to use plain HTTP connections,
thus enabling upload/download of charts from OCI registries served at
an HTTP endpoint.

During the install process there was a place where an install
process could be stuck trying to write to a channel. This would
happen when a context had completed prior to performInstall
finishing. In a short running Helm Client this was not a problem.
But, for long running applications that use Helm as an SDK there
are problems where a memory leak ends up happening due to
goroutines never being able to complete.
This fix provides a means for performInstall to write to its
channel using the method already used to fix the upgrade
issue of the same kind.

* Fixes Readiness Check for statefulsets using partitioned rolling update.
Fixes#11773
This change updates readiness check in ready.go to correctly
account for statefulsets that are utilizing a partitioned upgrade.
These statefulsets only upgrade a subset of the managed pods with each call
to helm upgrade. This causes the upgrade to legitimately hit the condition where
sts.status.CurrentRevision != sts.Status.UpdateRevision which causes helm to mark
the upgrade has failed when in fact it is successful.
This change fixes that behavior to only check when partition is unspecified or 0.

Go 1.20 introduced DNS/CNAME handling changes. This can cause an
IP address represented in hex, oct, etc to be looked up as DNS and
fail. This change introduces a mock DNS resolver.
Note, with the mock resolver, we don't need to use 0x7f000001 any
longer. Keeping because it was already there.

At this time both Go 1.19 and 1.20 are supported. The version
specified in the go.mod file is the minimum version we expect Helm
to be compiled against. This is the oldest supported version to
support environments where others compile Helm. The Helm project
is using Go 1.20 to build Helm itself.
Updating to Go 1.19 also includes dealing with io/ioutil
deprecation and some additional linting issues around staticcheck.
All the staticcheck issues were in test files so linting was
skipped for those.

As the CRDs are installed before the capabilities are gathered, the
current call to invalidate the discovery client is premature and
expensive.
What actually is required is an invalidation of the REST mapper, as
otherwise the Helm install action may later on fail with a `resource
mapping not found` error. More specifically when the caller of the
action is making use of a persisting[1] `RESTClientGetter`.
Which is not something done by the Helm CLI (albeit it could, and this
would potentially save quite some resources?). But is a default
configuration offered by the Helm SDK via `kube.New` when a nil value
is provided as the `getter`.
