These are equivalent to using the `start`, `restart`, and `stop` commands on the service specified

by the _value_ of the property.

`oneshot_one` and `oneshot_off` will turn on or off the _oneshot_

flag for the service specified by the _value_ of the property.  This is

particularly intended for services that are conditionally lazy HALs.  When

they are lazy HALs, oneshot must be on, otherwise oneshot should be off.
