Add listen/listen_in support to stateconf.py

[themalkolm]

Add listen/listen_in everywhere where watch/watch_in is used.

What does this PR do?

Adds listen/listen_in support to stateconf renderer. I blindly added listen everywhere where watch\watch_in is used. Please don't believe me and find somebody who can either verify or reject this.

It does work for me, though. I assume stateconf renderer was written before listen_in was added:

• stateconf first commit was made on Oct 30, 201226fa7e1
• listen_in was added in 2014.7.0 according to docs https://docs.saltstack.com/en/latest/ref/states/requisites.html#listen-listen-in

But oh well, I'm not sure about it.

What issues does this PR fix or reference?

stateconf renderer doesn't work in listen and listen_in fields. This is a naive attempt to fix it. Not sure it is done the right way, though.

@themalkolm You are dead on here! This should cleanly add listen into the checks, thanks!
