## What this PR does
This PR introduces a bare-bones Job backup strategy API type and stubs
out all the boilerplate for a new controller that will handle this
strategy, as well as any others in the `strategy.backups.cozystack.io`
API group.
### Release note
```release-note
[backups] Create stubs and minimal implmentations for controllers for
the strategy.backups.cozystack.io API group.
```
## What this PR does
This adds custom indexable fields on core backup resources to enable
filtering by backed-up application. This will later be useful for
displaying backup resources in the dashboard: it will be possible to
filter them with a field selector to display only those backup resources
that are relevant to a given application.
### Release note
```release-note
[backups] Enable filtering backup resources by backed up application for
per-app views of backups.
```
