Added SUSE support to apache cookbook

This adapts the apache cookbook to create a apache configuration on SLES good
enough for getting openstack-horizon dashboard running. Using SUSE's
default apache configuration layout, instead of adapting it to Debians/Ubuntu's
layout.

TODO: This is by no means complete and does not support all of the features
that this cookbook supports on Ubuntu.
SUSE support for rabbitmq cookbook

* Install rabbitmq package before touching any of its files
* the rabbitmq_management plugin in not available on SUSE, don't try to enable
  it there
* enable and start the "rabbitmq-server" service
Don't use bluepill on SUSE
Install rubygems from RPM on SUSE
Create Home directory when creating crowbar user

Add SUSE init script for crowbar (still needs work)

This invokes rainbows directly, it doesn't use bluepill (this is
intentional).  The stop and status functions don't currently work,
and a pidfile is not saved.  I suspect this is due to some
discrepancy between the init script specifying /usr/bin/rainbows,
but the running process only appearing as 'rainbows'.

Let crowbar write a pid file

- Only write pid file on "SUSE" on other distros bluepill will take care of
  creating the pid file
- Updated init script to use the correct pid file and executable name in
  "status" and "stop" actions.
- chef cookbook will now create /var/run/crowbar
