dependencies from OCI repositories.

If implemented this fix the issue where we previously did a string
ordering of matching semver versions when retrieving a list of tags from
an OCI registry.

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.

This new package holds all Helm OCI registry-specific code now so we
have a single location to look for such code which makes it easier to

* 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.

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.

If implemented, will provide users with a way to cache index files.
This addresses issues where the index file is loaded and unmarshalled in
concurrent reconciliation resulting in a heavy memory footprint.
The caching strategy used is cache aside, and the cache is a k/v store
with expiration.
The cache number of entries and ttl for entries are configurable.
The cache is optional and is disabled by default

If a local reference does not contain a path to a valid file, returning
`ErrChartReference` is more correct to signal the reference is invalid.
This also indirectly causes the reconciler to signal a Suspend, as the
source or resource requires a change before a reattempt might be
successful.

- Ensure all logged messages start with a lowercase.
- Make some pushed (and logged) events of type `EventTypeTrace` to

prevent spam.
- Only log if artifact is up-to-date with upstream (instead of pushing
an event).

Due to the temporary file having a random suffix, it would result in
the notification-controller not rate limiting the messages as they
are "unique".
For the close error (which also makes use of the name), we keep the
information as it might be of importance to figure out why the close

There was an unfinished code path that should have continued validating
the paths within the package. This commit completes it.

This makes it possible to signal reference (validation) errors
happening before the build process actually starts dealing with

At present, this does not have a more specific counterpart in the API,

This commit introduces a typed `BuildError` to be returned by
`Builder.Build` in case of a failure.
The `Reason` field in combination with `BuildErrorReason` can be used
to signal (or determine) the reason of a returned error within the
context of the build process.
At present this is used to determine the correct Condition Reason, but
in a future iteration this can be used to determine the negative
polarity condition that should be set to indicate a precise failure to
the user.

With all the logic that used to reside in the `controllers` package
factored into this package, it became cluttered. This commit tries to
bring a bit more structure in place.

This commit refactors the `ChartBuilder` that used to be a do-it-all
struct into an interace with two implementations:
- `LocalChartBuilder`: to build charts from a source on the local
filesystem, either from a directory or from a packaged chart.
- `RemoteChartBuilder`: to build charts from a remote Helm repository
index.
The new logic within the builders validates the size of the Helm size
it works with based on the `Max*Size` global variables in the internal
`helm` package, to address the recommendation from the security audit.
In addition, changes `ClientOptionsFromSecret` takes now a directory
argument which temporary files are placed in, making it easier to
perform a garbage collection of the whole directory at the end of a
reconcile run.

This commit starts with the creation of a `ChartBuilder` to facilitate
the (conditional) build of a chart outside of the reconciler logic.
The builder can be configured with a set of (modifying) options, which
define together with the type of chart source what steps are taken
during the build.
To better facilitate the builder's needs and attempt to be more
efficient, changes have been made to the `DependencyBuilder` and
`ChartRepository` around (order of) operations and/or lazy-load
capabilities.

This commits adds `LoadChartMetadataFromArchive` and
`LoadChartMetadataFromDir` helpers to the internal `helm` package
to be able to make observations to the Helm metadata file without
loading the chart in full.
The helpers are compatible with charts of the v1 format (with a
separate `requirements.yaml` file), and an additional
`LoadChartMetadata` helper is available to automatically call the
right `LoadChartMetadataFrom*` version by looking at the file
description of the given path.

As part of the feature implementation to support helm chart
dependencies, the functionality for allowing values files overwriting

chart itself is loaded.
