Initialize a service controlled by Monit.
``name``
Human-friendly name for the service.
``control_name``
Name that the underlying service control system uses to
identify the service.
``svc_args``
Command-line arguments specific to this service, in the
format expected by argparse_. Monit services require that
``svc_args`` contains a list of hosts on which you wish to
control services. Monit services also use the following
options, if provided:
``--username``
Username to use when authenticating to the Monit HTTP API.
``--password``
Password to use when authenticating to the Monit HTTP API.
``--port``
Port on which to connect to the Monit HTTP API.
``--realm``
Authentication realm to use when authenticating to the Monit
HTTP API.
