Projects:MMC Remove Rebuild and Restart/QA

Performance testing

It does not apply to this project, as it is a feature removal rather than adding a new one.

Automatic testing

MMC rebuild + restart was covered by CI tests. As pre-requisite for this project to be merged, these tests have been removed and replaced by cli ones.

Manual testing

Tested:

• Flows started from MMC UI and completed from CLI: install new modules, updates.
• Updating via MMC from an older version that already supported UI rebuild+restart: a proper error message is displayed.
