Update git submodules

* Update docs/submodules/genius from branch 'master'
  to d87b5785552cebd3aac6f16f7a610421ab8d95df
  - Remove deprecated utils in mdsalutil-api

    Listener base classes as well as FutureRpcResults are moved to genius/tools
    and all the usages are also migrated to the new utils. Let us remove
    the deprecated utils asap, so that new usages will not creep in :)
