Hidde Beydals 32e19ebcd0 controllers: more tidying of wiring
Dealing with some loose ends around making observations, and code
style.

The loaded byes of a chart are used as a revision to ensure e.g.
periodic builds with unstable ordering of items do not trigger a false
positive.

With all the logic that used to reside in the `controllers` package

Hidde Beydals 5a1fcc213b git: standardise commit and (PGP) verification
This commit refactors the previous `Commit` interface into a
standardised `Commit` struct. This object contains sufficient
information for referencing, observating and (PGP) verification.

- `libgit2` commit checkout does now return `HEAD/<SHA1>` as
  the branch is not taken into account.
- `git2go` objects are now properly `Free`d everywhere
- `Verify` logic is tested.

Dylan Arbour 27c385b957 Add ReconcileStrategy to HelmChart
This commit adds a `ReconcileStrategy` field to the `HelmChart` resource, which
allows defining when a new chart should be packaged and/or published if it
originates from a `Bucket` or `GitRepository` resource.

The two available strategies are:

- `ChartVersion`: creates a new artifact when the version of the Helm chart as
  defined in the `Chart.yaml` from the Source is different from the current
  version.
- `Revision`: creates a new artifact when the revision of the Source is
  different from the current revision.

For the `Revision` strategy, the (checksum part of the) revision of the
artifact the chart originatesfrom is added as SemVer metadata.

A chart from a `GitRepository` with Artifact revision
`main/f0faacd5164a875ebdbd9e3fab778f49c5aadbbc` and a chart with e.g. SemVer
`0.1.0` will be published as `0.1.0+f0faacd5164a875ebdbd9e3fab778f49c5aadbbc`.

A chart from a `Bucket` with Artifact revision
`f0faacd5164a875ebdbd9e3fab778f49c5aadbbc` and a chart with e.g. SemVer `0.1.0`
will be published as `0.1.0+f0faacd5164a875ebdbd9e3fab778f49c5aadbbc`.

Hidde Beydals 1f27410b34 Update Helm to v3.6.1
v3.6.1 is a a security update from Helm, ensuring that credentials are
always only passed to the defined repository host.

Based on Helm user reports, disabling this behavior may be required for
some Helm repository solutions like Artifactory, and may be done by
setting `PassCredentials` in the `HelmRepositorySpec`.

Hidde Beydals 917300dc79 Write chart data on identitical values overwrite
This likely happened because the byte buffer response was already
being read by the chart loader, making it empty by the time the
artifact was written to storage.

As an alternative, and because it makes the code a tiny bit less
obnoxious: write the data to a temp file first, and later decide
what file to copy over and use as an stored artifact.

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.

Fix HelmChart valuesFile chart path restriction
As part of the feature implementation to support helm chart
dependencies, the functionality for allowing values files overwriting
from any location scoped to the same source was altered. This should fix
the problem by allowing users to load files from any arbitrary location
as long as it's in the context of the same source from where the helm
chart itself is loaded.

Following the rules described in
https://helm.sh/docs/chart_best_practices/conventions/#chart-names.

This guards against people following the wrong guidance of Artifactory,
that supports and promotes repository indexes with e.g. '/' in the
chart names.

In a future version this should be moved to a validation webhook, but
there are still discussions ongoing around the TLS certificates for
this.

Remove use of chartutil.ProcessDependencies
It looks like the use of chartutil.ProcessDependencies in the HelmChart
Controller was not correct, this method seems to be used in Helm only
during install/upgrade. The intention was to load the dependencies but
this seems to not be needed as it's already done through the loaders
(loader.Load).

The use of this method caused a regression where Chart.yaml files would
be overwritten and registered subcharts that had aliases would be
renamed using the alias name. While this is an expected behaviour of
chartutil.ProcessDependencies it is not what the controller should do
to the chart during (re)packaging.
