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.

If implemented, the source controller will be able to resolve charts
dependencies from OCI repositories.
The remote builder has been refactored as part of this work.

* 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.

If implemented this will:
- enable the helmCharts dependency manager to use the helm in memry
cache to retrieve reconciled HelmRepositories indexes.
- record cache events.

This includes some rewiring of tests, and slight changes in how we work
with the local chart reference. `Path` is expected to be relative to
`WorkDir`, and both fields are now mandatory.

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

This makes it possible to signal reference (validation) errors
happening before the build process actually starts dealing with
the chart.
At present, this does not have a more specific counterpart in the API,
but this is expected to change when the conditions logic is revised.

- Add some more documentation around chart builders
- Ensure correct indentation in some doc comments
- Provide example of using `errors.Is` for typed `BuildError`
- Mention "bytes" in file size limit errors
- Add missing copyright header

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.

- For remote builds, if the build option has a version metadata, the
chart should be repackaged with the provided version.
- Update internal/helm/testdata/charts/helmchart-0.1.0.tgz to include
value files for testing merge chart values.

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.
