Initial steps towards getting replication working.
Replication now works for ubuntu.
Update Berksfile so the travis build doesn't error out.
Made it working on CentOS.
Added Centos config in Vagrantfile for experimentation.
Expose master IP as an input in ST (hack!)
Fix syntax error
Add master and slave recipes to metadata
Move setting bin logs to server recipe
Should be rs-mysql instead of rs_mysql
Revert "Move setting bin logs to server recipe"

This reverts commit 40f952d4ee10783cbf0eb812f1578fa7e2fc7556.
* Fix master/slave config file setup

* Move overriding mysql/tunable/server-id to server recipe
* Convert rightscale/server_uuid to an integer and use that as server-id
Should be rightscale/instance_uuid and not server_uuid
Add repl password and server uuid to .kitchen.yaml file
Add master suite to kitchen yaml, and new files for master tests
Add helper to get the server IP address. Override server-id in master
and slave recipes.
Add log messages for attribute overrides. Move binlog setup to server
recipe.
Switch to mysql2.  Test for read_only flag is working
Add test for binlog_format == MIXED
Check parameters using a hash, more efficient
