Subcloud Name Reconfiguration

This change adds the capability to rename the subcloud after
bootstrap or during subcloud rehome operation.

Added a field in the database to separate the region name
from the subcloud name.
The region name determines the subcloud reference in the
Openstack core, through which it is possible to access
the endpoints of a given subcloud. Since the region name
cannot be changed, this commit adds the ability to maintain
a unique region name based on the UUID format, and allows
subcloud renaming when necessary without any endpoint
impact.
The region is randomly generated to configure the subcloud
when it is created and only applies to future subclouds.
For those systems that have existing subclouds, the region
will be the same as on day 0, that is, region will keep the
same name as the subcloud, but subclouds can be renamed.

This topic involves changes to dcmanager, dcmanager-client
and GUI. To ensure the region name reference needed by the
cert-monitor, a mechanism to determine if the request is
coming from the cert-monitor has been created.

Usage for subcloud rename:
dcmanager subcloud update <subcloud-name> --name <new-name>

Usage for subcloud rehoming:
dcmanager subcloud add --name <subcloud-name> --migrate ...

Note: Upgrade test from StarlingX 8 -> 9 for this commit
is deferred until upgrade functionality in master is
restored. Any issue found during upgrade test will be
addressed in a separate commit

Test Plan:
PASS: Run dcmanager subcloud passing subcommands:
      - add/delete/migrate/list/show/show --detail
      - errors/manage/unmanage/reinstall/reconfig
      - update/deploy
PASS: Run dcmanager subcloud add supplying --name
      parameter and validate the operation is not allowed
PASS: Run dcmanager supplying subcommands:
      - kube/patch/prestage strategies
PASS: Run dcmanager to apply patch and remove it
PASS: Run dcmanager subcloud-backup:
      - create/delete/restore/show/upload
PASS: Run subcloud-group:
      - add/delete/list/list-subclouds/show/update
PASS: Run dcmanager subcloud strategy for:
      - patch/kubernetes/firmware
PASS: Run dcmanager subcloud update command passing --name
      parameter supplying the following values:
      - current subcloud name (not changed)
      - different existing subcloud name
PASS: Run dcmanager to migrate a subcloud passing --name
      parameter supplying a new subcloud name
PASS: Run dcmanager to migrate a subcloud without --name
      parameter
PASS: Run dcmanager to migrate a subcloud passing --name
      parameter supplying a new subcloud name and
      different subcloud name in bootstrap file
PASS: Test dcmanager API response using cURL command line
      to validate new region name field
PASS: Run full DC sanity and regression
