Add lifecycle to Component about spots

@zenangst I like this idea 😉

I updated the initial description to reflect the new naming.

I guess this could be introduced after 6.0.0 is released.

After thinking this over and having a chat with @vadymmarkov, I'm a bit on the fence if this would be useful. The way we currently build applications, we never really manually create Component's, instead we work with ComponentModel's. So it would be kinda redundant to add a life cycle as it would pretty much work in the same way as if we just subclass the SpotsController and rely on the view controller's life cycle.

Closing this for now, we can revisit this later if we deem it useful.
