The DB creation task should only be executed once and ideally from a
single neutron-server host otherwise it's possible to hit a race condition
where multiple neutron server hosts try to create the same DB at the same
time and only one will eventually succeed leading to task failures such
as the following one:
TASK [os_neutron : Create DB for service] **************************************
changed: [server2]
fatal: [server1]: FAILED! => {...}
