    Add default value to agent create_or_update_agent new param

    Commit Ifc88dfb3041aa07b197f395172b69399796ba46a recently added a
    new agent_timestamp parameter to create_or_update_agent.
    As some other projects use this api, the change should have been
    backwards compatible.
    Adding default to None will solve this issue.
