glance store initialization should be improved

[Stuart McLaren]

Currently the glance store initialization is explicitly called in the api start script:

 cat glance/cmd/api.py
 .
 .
 .

        glance_store.register_opts(config.CONF)
        glance_store.create_stores(config.CONF)
        glance_store.verify_default_store()

Other parameter's are picked up for free if we perform a configuration reload on sighup (eg sqlalchemy settings).
(An exception is logging where a log.setup() needs to be called).

It would be great, in order to fit cleanly with configuration reload, to have the glance_store initialization be called automatically, triggered by the eventlet.wsgi.server() call in glance.common.wsgi.

FWIW somewhat equivalent bug for osprofiler: https://bugs.launchpad.net/osprofiler/+bug/1407649

Flavio are you working on this?

Cindy (cpallares) is working on this as part of the glance_store refactor.
