Subject: [PATCH] Allow mysql_username and mysql_password to be passed via env
 var.

This change allows mysql_username and mysql_password to be passed to
bifrost-ironic-install via the environment variables mysql_user and
mysql_pass. This is useful when there is a preexisting mysql installation
with passwords alreay set.
