Long usernames can cause containers to fail creation.

[nrb]

In trying this, I was getting the following errors because of my longer username:

"ERROR: Inventory script (inventory/dynamic_inventory.py) had an execution error: The resulting combination of [ "nolan.brubaker-ord-aio1-development" + "nova_scheduler_container" ] is longer than 52 characters. This combination will result in a container name that is longer than the maximum allowable hostname of 63 characters. Before this process can continue please adjust the host entries in your "openstack_user_config.yml" to use a short hostname. The recommended hostname length is < 20 characters long."

Maybe truncate the username to something like 5 characters?
