Update git submodules

* Update docs/submodules/multicloud/framework.git from branch 'master'
  to fc2a18c1a384786874fe2a6b0ca543dfaa16a7de
  - Merge "Create definitions for multiple vf-modules"
  - Create definitions for multiple vf-modules

    This fix does not change distribution when there is one
    dummy heat and one cloud technology artifact.

    When there is more than one dummy heat or more than one
    cloud technology artifact forwarder will try to match them
    base on the name of the heat file that should match the prefix
    of the name of cloud artifact. There is no need to change use
    cases of vFW and EdgeX showcased for Dublin and ElAlto neither
    their descriptions should be changed.
