Switch config file.recurse to clean by default and tell it to ignore _*

[bugfix] Reverts lookup of salt_cloud_certs to original pillar key, in line with ...

Please refer to issue https://github.com/saltstack-formulas/salt-formula/issues/113.

Fix recursion in api.service

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 to install gitfs backend dependencies

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

Add setting to not install packages

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.

Stop using clean: True on /etc/salt/{minion,master}.d

Add note explaining what clean_config_d_dir does and why you shouldn't set it
to True.

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.

Don't overwrite salt variable

named salt.
