Add a Fabric task to mount encrypted MongoDB drive

alexmuller · alexmuller · commit a37dc353d82f · 2015-06-17T09:19:54.000+01:00
This task first checks whether the drive is already mounted. If it
doesn't do this check, it will remove stop MongoDB and remove all
the data from the encrypted drive.

Mounting the encrypted drive asks for a passphrase through Fabric,
which just works.
