Alex Schultz 8adb596e33 Switch heat-engine workers to use os_workers_heat_engine
Previously the default value for the heat-engine workers setting was set
to $::os_service_default. We usually use our specific facts for the
worker settings so this change switches it to use the
$::os_worker_heat_engine fact.

Previously the number of heat engine workers was set to $::os_service_default
which would use the default from python. Usually this means it will use
the number of processors in the system. We have found that this is not an
ideal default for large number of cpu systems. We have a provided fact
specific to heat engine named $::os_workers_heat_engine. We have changed
the default value for the heat engine works to use this fact. This
fact will cap the value at 24 but usually is the larger of
(number of procs / 2) or 4.
