moved cmc from api_manager to progress

@mattdrayer moved CMC from api_manager to progress. Added a command `move_cmc_entries` to move current data from api_manager to progress. Steps are 

1) Enable progress app and run migration on progress app to create tables
2) run command to move data from old to new table
3) Run migration on api_manager to remove old table
`projects` app can be switched on/off with feature flag.
