The salt-cloud packages automatically pull in the pycrypto and libcloud
dependencies for RedHat and Debian (at least when using the SaltStack
repos), so it doesn't really make sense to install these dependencies
using pip. By default we no longer use pip, but the old behaviour can be
restored by setting 'salt:use_pip' to True in the pillar.

There could probably be a case made for removing the pip stuff
altogether, but we will leave it in for the time being to preserve some
backwards compatibility.

This change tweaks the GitPython package installation state to support
alternate package names (on FreeBSD, it's called "py27-GitPython").
Also, on FreeBSD salt-ssh is included in the "py27-salt" package by
default, requiring an update to `distro_map`.

This obsoletes the salt:cloud:folders and salt:cloud:providers pillar
entries. Provider keys have been moved to /etc/salt/pki/cloud.

Salt writes it's schedule file to /etc/salt/{minion,master}.d/_schedule.conf

We don't want to stomp all over Salt's files, but we do want a pristine
starting point to lay down our managed config. So we use clean: True on the
file.recurse call, but we tell it to ignore files that start with an _

We have to rename the current config file (_defaults.conf) because it will be
ignored by the rule that ignores Salt's _* config files.

This also means we need to clean up old config files (_defaults.conf) and
restart the service if we cleaned it up.

Add modules for gitfs dependencies and documentation for how to use them.

If you are installing Salt via git/pip, the formula will try to overwrite your
install with packaged versions. This setting makes it possible to avoid that.

New versions of Salt put config files in /etc/salt/{minion,master}.d. We don't
want to erase them by using a clean: True on the file.recurse. This is a
backward incompatible change, but it's necessary to avoid deleting Salt config
files.

Resolves #104

Using a variable named salt is a bad idea when salt already has a variable
named salt.
