Added Propellor.Property.Spin, which can be used to make a host be a controller of other hosts.
The hard part of this is avoiding loops of controllers. To make that work,
a ControllerChain is passed to the host that's spun, and is added to the
Info of the host being spun, where the controller property can check it
to detect an avoid a loop.
That needed an expansion of the CmdLine data type. I made the new
ControlledRun only be used when there is a ControllerChain provided.
This avoids breaking backwards compatability with old propellor
deployments, as --spin still uses SimpleRun.
Note: Making an old propellor deployment be controlled by a controller
won't work until it's been updated to this commit, so it knows about
the ControlledRun parameter.
(Untested)
