Cache HelmRepository index files
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

Implement Managed Transport for libgit2
libgit2 network operations are blocking and do not provide timeout nor context capabilities,
leading for several reports by users of the controllers hanging indefinitely.

By using managed transport, golang primitives such as http.Transport and net.Dial can be used
to ensure timeouts are enforced.

Hidde Beydals dd68cd57b7 Rewrite `HelmRepositoryReconciler` to new standards
This commit rewrites the `HelmRepositoryReconciler` to new standards,
while implementing the newly introduced Condition types, and trying to
adhere better to Kubernetes API conventions.

More specifically it introduces:

- Implementation of more explicit Condition types to highlight
  abnormalities.
- Extensive usage of the `conditions` subpackage from `runtime`.
- Better and more conflict-resilient (status)patching of reconciled
  objects using the `patch` subpackage from runtime.
- Proper implementation of kstatus' `Reconciling` and `Stalled`
  conditions.
- Refactoring of some Helm elements to make them easier to use within
  the new reconciler logic.
- Integration tests that solely rely on `testenv` and do not
  use Ginkgo.

There are a couple of TODOs marked in-code, these are suggestions for
the future and should be non-blocking.
In addition to the TODOs, more complex and/or edge-case test scenarios
may be added as well.

  and downloading of object files in parallel with a limited number of
  workers (4).

Hidde Beydals 349739b7e4 Implement new runtime interfaces, prepare testenv
This commit ensures all API objects implement the interfaces used by
the runtime package to work with conditions, etc., and prepares the
test suite to work with the `pkg/runtime/testenv` wrapper.

Changes are made in a backwards compatible way (that being: the
existing code can still be build and works as expected), but without
proper dependency boundaries. The result of this is that the API
package temporary depends on the runtime package, which is resolved
when all reconcilers have been refactored and the API package does
no longer contain condition modifying functions.

Hidde Beydals fda481efe9 Upgrade controller-runtime to v0.7.0
This commit upgrades the `controller-runtime` dependency to `v0.7.0`,
including all changes required to make all wiring work again.

- Upgrade `runtime` to v0.6.0 to include `controller-runtime` changes.
- Loggers have been removed from the reconcilers and are now retrieved
  from the `context.Context` passed to the `Reconcile` method and
  downwards functions.
- Logger configuration flags are now bound to the flag set using
  `BindFlags` from `runtime/logger`, ensuring the same contract across
  GitOps Toolkit controllers, and the `--log-json` flag has been
  deprecated in favour of the `--log-encoding=json` default.
- The `ChangePredicate` from `runtime` has changed to a
  `ReconcilateAtChangedPredicate`, and is now chained with the
  `GenerationChangedPredicate` from `controller-runtime` using
  `predicate.Or`.
- Signatures that made use of `runtime.Object` have changed to
  `client.Object`, removing the requirement to e.g. call
  `runtime.Object#Object`.
- The `client.MatchingField` function was deprecated, and has been
  replaced with `client.MatchingFields{}`.
- The `leader-election-role` was changed, as leader election now works
  via the `coordination/v1` API.

Other notable changes:

- `util.ObjectKey` was added to easily construct a `client.ObjectKey` /
  `types.NamespacedName` from a `metav1.Object`.
- The `SourceIndexKey` constant has been split out into
  `{GitRepository,HelmRepository,Bucket}IndexKey` constants.

Hidde Beydals fa71f3269b Allow overwrite of advertised storage addr
The added `--storage-adv-addr` flag allows overwriting the HTTP address
advertised in the status objects of the sources. This allows for finer
grain configuration in setups where a modified service is used, or where
the DNS resolution differs from the Kubernetes defaults.

When the flag is omitted, an attempt is made to determine the address
based on the configured `--storage-addr` and the `HOSTNAME`.

- Add the HelmChart types and controller
- Semver expressions are found by utilizing Helm repository index

- Recorded semver is as defined in the metadata of the chart. The
  used name for the artifact does however include the checksum of the
  chart archive, as chart maintainers may not always properly apply
  semver.
- Switches to `sigs.k8s.io/yaml` for YAML operations as this among
  other things is able to properly unmarshal embedded structures.
- Directly requeues on transient errors instead of using the defined
  interval as a back-off strategy is applied on repeated failures.
