Scala Stream Collector: move cross domain configuration to enabled-style

At the moment, there are configurations which are defined as:

x {
  enabled = true/false
  restOfTheConfig = ...
}

and others defined as:

x {
  restOfTheConfig = ...
}

and its presence or absence determines if the feature is used.

We should pick one and stick to it.

I tend to prefer the second one as less stuff you don’t care about gets in your way.

wdyt @chuwy @alexanderdean ?

At least in JSON configurations we prefer first approach (even have linter for that). I also think that first approach is more explicit.

Not sure. Your call.
