Make Browbeat multi-cloud friendly.

This commit "localizes" ssh-config and heat-admin-id_rsa to your local
Browbeat directory.

This allows one to simply cd into the directory of the cloud they are
working with Browbeat against and ensure they do not incorrectly run
playbooks against the wrong hosts.

Example:

[akrzos@bithead ansible]$ ./generate_tripleo_hostfile.sh x.x.x.x
...
[akrzos@bithead ansible]$ ls -la
...
-rwxrwxr-x.  1 akrzos akrzos 9461 Aug 25 16:18 generate_tripleo_hostfile.sh

[akrzos@bithead ansible]$ ansible-playbook -i hosts install/collectd-openstack.yml
...

Tested against the collectd-openstack and grafana-dashboards playbooks

Potential issues:

CI? (Does CI execute any playbooks from the ansible directory?  If so
we shouldn't have an issue here.)

lib/{ansible/adjustments} - Can we make sure to pass the either the
correct ssh-config or use the ansible.cfg inside ansible/?

+Working with Multiple Clouds
+============================
+
+If you are running playbooks from your local machine you can run against more
+than one cloud at the same time.  To do this, you should create a directory
+per-cloud and clone browbeat into that specific directory:
+
+::
+
+    [browbeat@laptop ~]$ mkdir cloud01; cd cloud01
+    [browbeat@laptop cloud01]$ git clone git@github.com:openstack/browbeat.git
+    ...
+    [browbeat@laptop cloud01]$ cd browbeat/ansible
+    [browbeat@laptop ansible]$ ./generate_tripleo_hostfile.sh <cloud01-ip-address>
+    [browbeat@laptop ansible]$ ansible-playbook -i hosts (Your playbook you wish to run...)
+    [browbeat@laptop ansible]$ ssh -F ssh-config overcloud-controller-0  # Takes you to first controller
+
+Repeat the above steps for as many clouds as you have to run playbooks against your clouds.
