Salman Rana 7d44c38c90 Introduce dccertmon service
This commit introduces dccertmon, a new managed service for DC
certificate auditing and management.

Currently, platform cert management, DC cert management, and subcloud
cert auditing are coupled into a single platform service (certmon). To
meet the requirements of DC scalability and portability, DC specific
functionality must be decoupled. These changes lay the groundwork
for the new service, by:
- Creating the necessary service files.
- Introducing configs for the service.
- Declaring high level methods (Skeleton - lifecycle and manager)

DC-specific functionality will be migrated to this dccertmon service and
optimized in subsequent changes. Non-DC cert management will continue to
be handled by certmon.

Overall, this commit introduces:
- The OCF file necessary for high availability management of the
  dccertmon service by SM.
- Package configurations to build the service (Package: distributedcloud-dccertmon).
- Lifecycle manager for a running DC cert monitor service.
- Skeleton/base service application logic - CertificateMonitorManager.
- RPC notification handlers for subcloud online/managed.
- Configuration for the log folders and log rotation. The logs
  will be available in /var/log/dccertmon/dccertmon.log.

These changes are part of a set of commits to introduce the dccertmon service:
  [1] https://review.opendev.org/c/starlingx/ha/+/941205
  [2] https://review.opendev.org/c/starlingx/stx-puppet/+/941208

Test Plan:
  - PASS: Build dccertmon package
  - PASS: Install and bootstrap system with custom ISO containing the
          newly created dccertmon package
  - PASS: Verify that the dccertmon.service is loaded
  - PASS: Verify dccertmon is being properly logged to the correct
          folder.
  - PASS: Check logged messages and verify execution of
           - Cert Watcher thread
           - Task Executor (Audit thread)
           - Periodic tasks running at expected intervals
  - PASS: Configure and provision the service using SM and verify
          it has correctly started and can be restarted with
          'sm-restart'.
  - PASS: Tox checks running on dccertmon

  Note: This commit has been tested alongside the related changes and
        their respective test plans. [1][2]
