    Add GLANCE_LOCALEDIR env variable

    Part of fixing bug #995287

    Syncs these two commits from oslo-incubator:

      Support overriding oslo localedir too
      Add a gettextutils.install() helper function

    to get a new gettextutils.install() function which allows the default
    localedir to be overwritten via an environment variable.

    Note that gettextutils.install() must be called before any other glance
    modules are imported since some modules attempt to translate strings
    at import time (e.g. the help strings for config options in config.py).
    This is broken and inefficient, but fixing it involves adding something
    like spinx's l_() function and would be very invaisve.

    Also, note that calling gettextutils.install() in glance.cmd.__init__
    means that no program which uses a different translation domain should
    ever import any of the modules under glance.cmd.
