Update git submodules

* Update docs/submodules/snaps from branch 'master'
  - Merge "SNAPS Stack creators can now return SNAPS network creators."
  - SNAPS Stack creators can now return SNAPS network creators.

    As Heat Stacks are responsible for spawning objects in OpenStack,
    the class OpenStackHeatStack which is responsible for applying and
    managing the state of a stack now can retrieve OpenStackNetwork
    objects for the networks created in the stack for clients who would
    like to query the networks and subnets or update them outside of
    Heat.
