Updated distcloud for subcloud region_name changes

There has been a breaking change in the distcloud package.

In the O2 code it's assumed the subcloud_name == subcloud_region_name.
This is no longer true or the default.

PASS: Run docker-compose unit testing
PASS: Run compliance and quality robot tests, with mock SMO
* Deploy oran-o2 application on StarlingX system controller (stx9)
* Update/apply override for dev image
* Ensure O2 pod is running using correct image
