During startup of nova-compute, we see the following error message:
Error gathering result from cell 00000000-0000-0000-0000-000000000000:
DBNotAllowed: nova-compute
This issue was observed in devstack [1], and fixed [2] by removing
database configuration from the compute service.
This change takes the same approach, removing DB config from nova.conf
in the nova-compute* containers.
