  - Merge "Fix for appc clustering install failure"
  - Fix for appc clustering install failure

    Update appc karaf stop detection
    The new stop detection script is more reliable and
    does not depend on a specific value and format of
    the ps command.

    Remove clustering feature install
    The feature needs to be installed before appc features
    are installed, and so the odl-mdsal-clustering install
    has been moved to the build scripts.
