Provide sample environment for composable roles

Creating a sample environment generator configuration to generate basic
environment files for the following architectures:

 * Monolithic HA (3 Controller, 3 Compute, 1 Ceph)
 * Monolithic Non-HA (1 Controller, 1 Compute, 1 Ceph)
 * Standalone (3 Controller, 3 Database, 3 Messaging, 2 Networker,
   1 Compute, 1 Ceph)
