Revert "Use uwsgi for glance-api"

This reverts commit e6217a9719b88b550ccbbce7c9bc064cb746c1a3.

Unfortunately it seems to break glance; for examples see some of the
nodepool dib jobs which have all failed to upload images into glance.

Note this has a revert for 43304849cfde41fa86a6fdd334ab6e703598ef8d as
well, since that uses GLANCE_URL defined here.
