This allows the server delete command to wait for the server to be deleted (obviously). The wait method is the same model that Tempest uses, i.e. wait for a 404 on server GET (successful deletion), fail if the server went to ERROR status, or fail if a timeout is reached. The default timeout of 300 seconds is also what Tempest uses. Closes-Bug: #1460112 Change-Id: I0e66c400903e82832944d1cad61e7eb30177c3e8
