enables use of jinja < 2.6

Commit 2b51a6f0c3 introduced options for gitfs_remotes in a pillar by using a jinja test to see if a parameter is a mapping (dict etc.). This feature however is only available in jinja 2.6 or newer (see http://jinja.pocoo.org/docs/dev/templates/#mapping).
Although this version of Jinja is available on Ubuntu, other OS / package managers do provide older versions (2.2.1 in RedHat 6).

This change makes use of the "iterable" test which should do the exact same thing.

Removed crypto dependency from salt.cloud.

It doesn't seem to be available from pip anymore, and may not be
a real dependency. Salt-cloud certainly seems to work fine without
it.

Add salt.ssh state for installing and configuring salt-ssh
