+# ========

+# Get a token for clients that don't support service catalog

+# ==========================================================

+

+# manually create a token by querying keystone (sending JSON data).  Keystone

+# returns a token and catalog of endpoints.  We use python to parse the token

+# and save it.

+# ------
