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 nova modules are imported since some modules attempt to translate strings at import time (e.g. the 'message' attributes on classes in nova.exception). 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 nova.cmd.__init__ means that no program which uses a different translation domain should ever import any of the modules under nova.cmd.
