    # Usage jenkins-agent.sh [options] -url http://jenkins [SECRET] [AGENT_NAME]
    # Optional environment variables :
    # * JENKINS_TUNNEL : HOST:PORT for a tunnel to route TCP traffic to jenkins host, when jenkins can't be directly accessed over network
    # * JENKINS_URL : alternate jenkins URL
    # * JENKINS_SECRET : agent secret, if not set as an argument
    # * JENKINS_AGENT_NAME : agent name, if not set as an argument
    # * JENKINS_AGENT_WORKDIR : agent work directory, if not set by optional parameter -workDir
    # * JENKINS_DIRECT_CONNECTION: Connect directly to this TCP agent port, skipping the HTTP(S) connection parameter download.
    #                              Value: "<HOST>:<PORT>"
    # * JENKINS_INSTANCE_IDENTITY: The base64 encoded InstanceIdentity byte array of the Jenkins master. When this is set,
    #                              the agent skips connecting to an HTTP(S) port for connection info.
    # * JENKINS_PROTOCOLS:         Specify the remoting protocols to attempt when instanceIdentity is provided.
