Carl Baldwin 3d669cbd0e Creates multiple worker processes for API server ...

This change to the WSGI code uses openstack.common.service to create
multiple worker processes to handle API load.  The main process will
start up a configurable (workers=??) number of child processes which
will all listen on the bind port.  The main process becomes the parent
and manages the children.  The parent is not a worker.

Backwards compatibility is preserved by setting api_workers to 0, the
default.  In this case, no separate worker processes are spawned and
the worker threads run in the main process.
