  - Bump jersey-1.x to 1.19.4 and package it

    Rather than relying on downstreams doing their own packaging
    of jersey, provide proper package of basic dependencies in a feature.

  - Align jetty version with karaf

    karaf is pulling in version 9.3.21, while we are advertizing
    9.2.19 -- which leads to odl-karaf-feat-jetty not squashing
    dependencies in features.
