Add databases plugin v0 (android) (#441)

Browse Source 
Summary:
Adds a plugin for listing the databases, tables and contents of those tables in an android app.
Right now, works with sqlite, but it should be generic enough to work with other db types.

## Changelog

Add initial version of android databases plugin

Creating a PR, I may need to do some cleaning up, but this is to kick off that process.
