Implement tunable heat api and engine worker overrides

Browse Source 
This patch introduces an override for the number of Heat engine and
Heat API workers:
 - heat_engine_workers
 - heat_api_workers

The values may be set in /etc/openstack_deploy/user_variables.yml
and if they are unset, half the number of available vCPU's will be
used instead.

Implements: blueprint gate-split
