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#11805

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`.

If enabled the registryClient is set using a helper that accepts the TLS
flags. This keeps the client creation consistent accross the different
commands.

When range support for OCI went in via #10527 it created a situation
where some lookups for a chart could cause a panic. This change
makes sure the registry client is available to lookup OCI charts

Note: OCI support remains experimental, and you are still
required to set HELM_EXPERIMENTAL_OCI=1 in your environment.

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.

A chart being installed which only contains CRDs and not
any templates tries to install the resources by default.
The resourceList which is used in this case does not check
if there are resources present in it or not. This commit
adds checks to those particular places where we need to check
if the size of resourceList > 0 during installation and deletion.
