Initial public commit of mgmt

This is a prototype that i'm attempting to "release early". Expect a lot
of changes! It is intended to be a config management tool that will:

* be event based
* execute actions in parallel
* function as a distributed system

There are a bunch more design ideas going into this, please stay tuned!
