Chris Dent b90bb1a461 Use uwsgi for nova when NOVA_USE_MOD_WSGI is not False ...

Unless NOVA_USE_MOD_WSGI is False, run nova-api and nova-metadata
using uwsgi.

Because the metadata server is always expected to run on a port and
without a prefix, we have it configured to use uwsgi but not to
proxy from apache: uwsgi listens on the configured port itself.

uwsgi process that listen themselve do not need a socket or to
chmod-socket, so those config lines have been moved to the block
that is also writing proxy configuration for apache.

Because this change only uses uwsgi for nova-api and nova-api-meta,
nova-api-meta is set to default to enabled in stackrc because the
nova-api wsgi application used by wsgi only presents the one service
(osapi_compute).

If NOVA_USE_MOD_WSGI is False and tls_proxy service is enabled,
nova-api is run on an internal port reached via the tls_proxy.
