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.

Rather than use simple_cell_setup which expects that there are already
existing computes, this change uses map_cell0 & create_cell to setup
cell_v2. Once the computes are configured, the cell_v2 discover_hosts
should be used to finalized the installation.
In addition, the db syncs need to be reordered as the api db sync
should run before the the cell_v2 setup. The main db sync should run
after.
map_cell0/simple_cell_setup now uses main nova DB connection instead
of the api DB connection.

As Openstack projects continue to have longer database migration
chains, the Puppet default timeout of 300 seconds for an execution
is becoming too short a duration on some hardware, leading to timeouts.
As projects continue to add more migration scripts without "pruning"
the base, timeouts will continue to become more frequent unless
this time can be expanded.
The proposed change adds a configuration option db_sync_timeout
which maintains the Puppet default of 300 but allows TripleO to
change the timeout to something higher.

In order to standardize the way dbsync are run across our modules,
we create a new class nova::db::sync.
This class will be included if sync_db is enabled.
By making this transition the nova::db::sync class
can be returned by the ENC.
A use case would be in an highly available environment, with 3 galera
nodes, include nova::api on every node with sync_db set to false
and have the ENC return nova::db::sync just for one node.
