Maksym Yatsenko 866aabb8bd Change worker defaults to ::os_workers
This patch changes the default worker count from ::processorcount to the
new ::os_workers fact. ::os_workers is based on the number of processors
(currently cpu/4) but is capped at a maximum of 8 worker processors.
This is a much more reasonable default in general and prevents excessive
resource consumption on systems with a large number of CPUs.

#
# Class to serve barbican with apache mod_wsgi in place of barbican service
#
# Serving barbican from apache is the recommended way to go for production
# systems as the current barbican implementation is not multi-processor aware,
# thus limiting the performance for concurrent accesses.
#
# When using this class you should disable your barbican service.
