helmrepo: fix Secret type check for TLS via `.spec.secretRef`
This is a regression fix introduced in a302c71 which would wrongly check
for the type of the Secret specified in `.spec.secretRef` while
configuring TLS data.

Introduce `LegacyTLSClientConfigFromSecret` which does not check the
Secret type while constructing the TLS config.

`tls.key` for the certificate and private key. Use `ca.crt` for the CA

Hidde Beydals c0a1099719 helm: only use Digest to calculcate index revision
In #1001 bits around the Helm repository reconciliation logic were
rewritten, mostly based on the documented behavior instead of the
actual code. This resulted in the reintroduction of a YAML marshal of
the (sorted) index YAML instead of reliance of just the checksum of the
file.

This to take situations into account in which a repository would e.g.
provide a new random order on every generation. However, this approach
is (extremely) expensive as the marshal goes through a JSON -> YAML
loop, eating lots of RAM in the process.

As the further (silently) introduced behavior has not resulted in any
reported issues, I deem this approach safe and better than e.g.
encoding to just JSON which would still require a substantial amount of
memory.

This includes changes to the `ChartRepository`, to allow calculating
the revision and digest and tidy things.

In addition, the responsibility of caching the `IndexFile` has been
moved to the reconcilers. As this allowed to remove a lot of
complexities within the `ChartRepository`, and prevented passing on
the cache in general.

Sunny 8018b450a1 helm: typed errors from GetChartVersion()
Update the implementations of the helm repository downloaders to return
implementation specific typed error from GetChartVersion(). This is
needed to distinguish between persistent build error and transient build
error.
In the case of OCI charts, a transient network failure shouldn't be
considered a persistent build failure of the chart and should be
retried.

Two repository errors, ErrReference and ErrExternal are introduced for
the repository downloader implementations to provide enough context
about the failure which can be used by the caller to add appropriate
context as per the needs. In case of chart builder, it adds the build
error context based on the repository error value.

add custom CA certificates to system certificates
When a custom CA certificate is provided in a Secret's `caCert` field
referenced in `HelmRelease.spec.secretRef` then that CA cert is now
added to the list of system certificates instead of it replacing the
system certificates. This makes HelmRepositories work in mixed
environments where charts are pulled from both, a public repository
and a private repository (e.g. through a chart dependency).

The test that is added as part of this change will fail without the
change and passes with it.

don't fetch tags when exact version is used in HelmRepository
Taking this shortcut has two benefits:

1. It allows charts to be fetched from AWS's public container registry
   at public.ecr.aws
2. It makes reconciling a HelmChart faster by skipping one or more
   potentially expensive API calls to the registry.

I adapted the unit tests to the new behavior that the
OCIChartRepository doesn't fail anymore for the case where a specific
chart version has been requested that doesn't actually exist in the
registry.

registry: repo URL and dockerconfig URL mismatch
Registry login option should verify that the obtained dockerconfig
credentials are for the same host. When the helmrepo URL and the URL in
docker auth config don't match, the docker config store returns an
empty auth config, instead of failing. This results in accepting empty
username and password. The HelmRepo would appear to be ready in such
situation because the creds are empty, no login is attempted. But when
a HelmChart tries to use the login options, it'd fail.

[RFC 0002] Flux OCI support for Helm (#690)
* Add OCI Helm support

* users will be able to declare OCI HelmRepository by using the `.spec.type` field of the HelmRepository API. Contrary to the HTTP/S HelmRepository no index.yaml is reconciled from source, instead a simple url and credentials validation is performed.
* For backwards-compatibility, an empty `.spec.type` field leads to the HelmRepository being treated as a plain old HTTP Helm repository.
* users will be able to declare the new OCI HelmRepository type as source using the .Spec.SourceRef field of the HelmChart API. This will result in reconciling a chart from an OCI repository.
* Add registryTestServer in the test suite and OCI HelmRepository test case
* Add a new OCI chart repository type that manage tags and charts from an OCI registry.
* Adapat RemoteBuilder to accept both repository types
* discard output from OCI registry client; The client has no way to set a verbosity level and spamming the controller logs with "Login succeeded" every time the object is reconciled doesn't help much.

test: use `T.TempDir` to create temporary test directory
This commit replaces `os.MkdirTemp` 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 `os.MkdirTemp`
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.

Avoid validating (and thus loading) indexes if the checksum already exists in storage.
In other words, if the YAML is identical to the Artifact in storage, the reconciliation should
be a no-op, and therefore can short-circuit long/heavy operations.
