Added port and db parameters to constructor.

class JobCache(object):

    def __init__(self, host):

    def __init__(self, host, port, db):

        self.host = host

        self.redisCli = redis.StrictRedis(host = self.host)

        self.port = port

        self.db = db

        self.redisCli = redis.StrictRedis(host = self.host, 

                                          port = self.port, 

                                          db = self.db)

    def set(self, jobObj):

        data = { "jobID": jobObj.jobID,
