  - Fix eelf resource not found

    The eelf package needs to be exported from appc-common
    where the resource bundle is added. Doing this was
    causing karaf to crash on install of artifact-handler.
    The cause was all of the classes being exported by the
    maven shade plugin of appc-yang-generator. Removing the
    shade plugin seemed to have no bad consequences.
