    METRON-1430: Isolate jackson from being used as arguments or returns from JSONUtils

    ## Contributor Comments
    Currently jackson is used as part of our internal API to JSONUtils.  The problem here
is when we shade and relocate jackson.  Suddenly we can't use JSONUtils.  We should avoid
operating on jackson primitives and rather provide a convenient wrapper around the places
where we use jackson as part of the API.
    This is required for #907 because this is where we are forced to relocate jackson and
there is a competing version on the classpath.
    Validate by running up vagrant and ensuring data flows through all topologies, data shows
up in the alerts UI.
