Summary:
this sets up the basic flow in the operator's reconcile phase. following diffs will actually implement each of these functions. the implementation of these functions will be heavily borrowed from our current deploy/update/delete in the CLI/updater job.
1. deletion: if the reconciler was triggered with a CRD that no longer exists
2. creation: if the reconciler was triggered with a CRD that has no known status.
3. update: if the reconciler is triggered with a CRD that does have a known status/deployed vizier.

Test Plan: ran skaffold, created a CRD with no version
