- Add the HelmChart types and controller
- Semver expressions are found by utilizing Helm repository index
helpers. As Helm makes use of `masterminds/semver`, the support
for i.e. ranges less mature than the `GitRepository` implementation.
- 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.
