What this PR does / why we need it:
Previously, the operator did not start before all needed CRDs were installed. This meant that it was not possible to remove an SSP resource if CDI was not installed.

This PR adds a CrdWatch component, which restarts the operator, if some needed CRDs are deleted while it is running.

Fixes: https://bugzilla.redhat.com/show_bug.cgi?id=2122236

Release note:

Operator properly handles missing CRDs.

watch required CRDs
37d0012 
Added a new component, CrdWatch, that watches CRDs in cluster.

If some of the needed CRDs are missing, the SSP reconciler runs
in a "cleanup only" mode, and does not reconcile any resources,
only deletes resources when a SSP resource is deleted.
