Most of openstack API units have a worker multiplier. If this is unset it will default to 4 workers for each API units. Most of clouds have at 0.25.
Default 4 workers is too less for a production cloud and we saw random http 502 when this was unset.
Juju lint should raise a warning/critical if this is unset especially for keystone, neutron-api and nova-c-c, cinder, octavia, placement, glance
