    METRON-1521: JSONMapParser is no longer serializable

    ## Contributor Comments
    Currently the JSONMapParser does not function because an anonymous inner 
class (TypeRef) is not serializable.
    * Create a new parser by editing 
`$METRON_HOME/config/zookeeper/parsers/dummy.json` to have the following 
      "fieldTransformations" : [
             { "transformation" : "STELLAR"
             ,"output" : [ "new_field"]
             ,"config" : {
               "new_field" : "JOIN( [ TO_UPPER(source.type), field ], ',' )"
    * Create the dummy kafka topic via 
`/usr/hdp/current/kafka-broker/bin/kafka-topics.sh --zookeeper node1:2181 
--create --topic dummy --partitions 1 --replication-factor 1`
    * Push the zookeeper configs via `$METRON_HOME/bin/zk_load_configs.sh 
--mode PUSH -i $METRON_HOME/config/zookeeper -z node1:2181`
    * Start the parser via `$METRON_HOME/bin/start_parser_topology.sh -k 
node1:6667 -z node1:2181 -s dummy`
    * Create some dummy data by creating a file at `~/dummy.dat` with the 
    { "field" : "f1", "source.type" : "dummy" }
    { "field" : "f2", "source.type" : "dummy" }
    { "field" : "f3", "source.type" : "dummy" }
    { "field" : "f4", "source.type" : "dummy" }
    { "field" : "f5", "source.type" : "dummy" }
    { "field" : "f6", "source.type" : "dummy" }
    { "field" : "f7", "source.type" : "dummy" }
    * Send the dummy data in via `cat ~/dummy.dat | 
/usr/hdp/current/kafka-broker/bin/kafka-console-producer.sh --broker-list 
node1:6667 --topic dummy`
    * Ensure the data written to the indices has a field `new_field` that looks 
like `DUMMY,${field}`
