Glance API version 1 is deprecated as of kilo. If we want to support v2 moving forward, we should add support for passing a version in to the glance module, and alter the module to take appropriate action depending whether we are using v1 or v2. This commit does that, defaulting to 1 to keep compatibility with current code in master. Change-Id: Iac9dcd3f5fdf1cfacde3e9cb10cb1aa2b72500a8 Closes-Bug: 1435808
