should Service be a state machine?

[progrium]

I've gone back and forth about this. Imagine a service with these states:

• idle
• starting
• ready
• stopping
• reloading

The require_ready decorator would wait for the ready state (although it could already do this). There could be a wait_for(state) method. Services could go out of ready state.

This is a more general solution to the issue here: https://github.com/progrium/gservice/issues/21

I think we decided yes to this. Here is an example:
