Update git submodules

* Update docs/submodules/snaps from branch 'master'
  - Fixed the Glance connection test routines.
    test_glance_connect_success gave a false positive and
    test_glance_connect_fail gave a false negative.
    Both were calling incorrect APIs due to copying from the equivalent
    nova_utils.py test.
