This is a feature needs to be discussed and well designed in the community,
no actual work has been done at the moment as no one else shows interest
and gets involved. I'm very happy to provide help if needed.

User and database management APIs are not supported as different datastores
have totally different management models, it was decided to not implement
such APIs in the future but let the trove users (db admin) manage users and
dbs by themselves.

For all your other questions not answered, they are all not implemented yet
given the resources the team has. If DBaaS is in your roadmap and Trove is
in your radar, I appreciate if you could get involved and start
