Enhancement: Get database information from _dbs_info

[popojargo]

With the recent release of 2.2.0, we can now query the information of multiple databases through this new endpoint: _dbs_info

We could replace the actual separated API call with this bulk call to reduce network requests.

Expected Behavior

We request the _dbs_info with the database names from the actual paging.

Current Behavior

We request the database information by querying each database separately.
