Trove/list-datastore-type-and-versions

Description

This blueprint will add an API call for retrieving datastore type and version in a single call.

Blueprint:

Justification/Benefits

• Instead of making n+1 calls where n is the number of datastore types, this single API call will fetch all datastore types and version, and the manager in a single call. It will also show if the version is the default for that datastore.
• This call can vastly improve the user experience for retrieving all the supported datastore types and versions
