tools: Add initial HyperKit/Moby InfraKit instance plugin

This is the first cut of a InfraKit instance plugin which
primarily allows one to manage Moby instances (though, other Linux's
may work too).

It's very rough on the edges and needs work and update to handle
templates and better configuration etc.
