Cant smoothly extend RestApplication without being stuck with RestComponent as well.

Wanting to extend RestApplication to override one or another method and I'd also like to extend RestComponent and override a thing or two. Not really seeing a way to do it with the way this is coded. There are a bunch of patterns that could rectify this. Instead I'm having to entirely copy the RestApplication class to achieve this.

Noting. Will add more detail shortly. :)

Thanks for opening a new issue, @roberttaylortech! I've not encountered the need to provide my own RestComponent, so I'm not aware of any existing way to do so, but I do believe this is something LoopBack 4 should support as part of its extensibility principles.

Noting. Will add more detail shortly. :)

I look forward to the additional details :-)
