This commit removes the usage of patch throughout DC applications,
deleting the patch orchestration and load and patch audits.
Note: this commit does not replace the usage of PatchingClient, which
will be done in a subsequent review.
Test plan:
1. PASS: Deploy a DC system.
2. PASS: Manage a subcloud and verify that all endpoints are set as
'in-sync'.
3. PASS: Run dcmanager subcloud show and verify that there are no
references to load and patch endpoints.
4. PASS: Unmanage a subcloud and verify that all endpoints are set as
'unknown'.
5. PASS: Create and apply a strategy, verifying it completes
successfully.
6. PASS: Execute a select statement in the subcloud_audits table and
verify that the patch_audit_requested and load_audit_requested
columns does not exist.
7. PASS: Perform a system upgrade successfully.
