Update git submodules

* Update docs/submodules/snaps from branch 'master'
  - Closing keystone sessions after done with them.
    
    By not closing all of the keystone sessions being created when
    running all of the tests, this may be the root cause to the IOError
    occasionally being observed:
    
    IOError: [Errno 24] Too many open files
