Write a lint rule that prevents endless loops

[sockeqwe]

A endless loop that causes a stackoverflow is possible if you write an action that produces the same kind of output as it also consumes as input. Example:

fun sideEffect1(actions : Observable<FooAction>, stateAccessor : StateAccessor<State>) : Observable<FooAction> = 
actions
    .ofType(FooAction::class.java)
    .map { FooAction() } // Endless loop

This reduces a endless loop because output is FooAction which then is also the input for the same SideEffect.
