This adds a `--interval-jitter-percentage` flag to the controller to
add a +/- percentage jitter to the interval defined in resources
(defaults to 10%).
Effectively, this results in a reconcilation every 4.5 - 5.5 minutes
for a resource with an interval of 5 minutes.
Main reason to add this change is to mitigate spikes in memory and
CPU usage caused by many resources being configured with the same
interval.

In Reconcile() methods, move the object deletion above add finalizer.
Finalizers can't be set when an object is being deleted.
Introduce a cacheless client in suite_test to use for testing this
change. It ensures that the Reconcile() call always operates on the
latest version of the object which has the deletion timestamp and
existing finalizer.

Add `.spec.proxySecretRef.name` to the `GitRepository` API to allow
referencing a secret containing the proxy settings to be used for all
remote Git operations for the particular `GitRepository` object.
It takes precedence over any proxy configured through enviornment
variables.

This adds a bit back which got removed in
69f567bdc7, as there are reasons for the
controller to perform a non-optimized clone.
However, we always want to attempt the optimized version first without
it being put behind a feature gate. Which was the original intent of
the referenced commit.

Remove the `OptimizedGitClones` feature gate, making optimized Git
clones when using a branch or tag to checkout, the default behavior.

This deals with various breaking changes in controller-runtime, as
documented in the release notes:
https://github.com/kubernetes-sigs/controller-runtime/releases/tag/v0.15.0
In short:
- `Watches` now use a `client.Object` instead of a `source.Kind`.
- `handler.MapFunc` signature accepts a Go context, which is used to
log any errors, instead of silently ignoring them and/or panicking.
- Fake clients used in tests are now configured using
`WithStatusSubresource` to enable the correct behavior for status
updates and patches.
- Max concurrent reconciles is configured on the manager, instead of
configuring them per reconciler instance.
- Various manager configuration options have been moved to new
structures and/or fields.
In addition to this, all other dependencies which had updates are
updated to their latest (compatible) versions as well.

This commits adds verification of the digest of the artifact in storage
to all reconcilers which manage artifacts.
When the artifact does not have a digest or if it mismatches with the
file in storage, the file is removed from the storage and status of the
object.
This hardens the storage against potential tampering, in addition to
resolving an issue where users upgrading from a (much) older version of
the controller would run into an error after the checksum field was
removed from the API.
This would cause the controller to not advertise any checksum at all,
while not producing a new one until a new revision was detected.
Resulting in fetch failures for consumers while they would try to
verify the digest of the advertised artifact.
While not strictly part of this exercise, some of the tests were
altered to prepare the storage used in test cases to become isolated
by strictly using the `storage` provided via the callback. Actually
isolating this has however been left as a task at a later moment.
