Title: Print error message if edx_ansible not installed in base box

In response to @yarko 's suggestion for issue https://github.com/edx/configuration/issues/564:

Added a check for the `edx_ansible` role in the release version of devstack. If the base box doesn't have `edx_ansible` installed, then fail immediately with an error message.
