This commit adds a timeout field to the GitRepositorySpec to be used
during the git clone operation when reconciling the resource.
When no interval is defined the default timeout returned by the getter
is 20 seconds.
The timeout can not be added yet to the Helm related sources as it
is currently not possible to inject anything custom into the HTTP
client from the Helm HTTP getter except for the authentication
options built in. A submit has been submitted to make this possible
and is waiting for review.
This commit includes some context changes to the other reconcilers
to tidy them up and make them depend on a single background context.
It also includes some added docblocks that crossed my path.
- 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.
