Drush Interface

[sherakama]

Hey,

I would like to open this ticket as a start to creating a Drush interface for this module. Some useful functions I can think of are:

1. Test & Authenticate with server.
2. Change endpoint.
3. Update and sync orgs.
4. Update and sync schema.
5. update and sync content.
6. Update and sync all the things.
7. Fetch & save [org | group | single]
