Test if individual gitfs remote is string

https://github.com/saltstack-formulas/salt-formula/issues/64

Fixes issue where a gitfs remote that has no child options would cause an
error. Also fix up bad yaml in pillar example.

adds `yaml_utf8` option to master config

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.

Revert "Removed crypto dependency from salt.cloud."

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

Fix YAML issue with templated reactor config

add templated file for reactor configuration and update pillar.example.

Allow individual repo options for gitfs_remotes

Vagrant

Readme note about user-provided configuration templates.

Added recursive management of minion.d and master.d.

This allows users to easily add configuration settings that the formula
doesn't yet provide, without having to modify the existing templates.

Added salt-cloud support for Rackspace OpenStack servers.
