Update git submodules

* Update docs/submodules/snaps from branch 'master'
  - Refactoring of VmInstanceSettings to extend VmInstanceConfig
    
    VmInstanceSettings, FloatingIPSettings and nova_utils have a
    runtime cyclical dependency. This patch reduces this dependency and
    deprecates the VmInstanceSettings and FloatingIPSettings class with
    snaps.config.vm_inst VmInstanceConfig and FloatingIpConfg classes
