A lifecycle page in the docs

I believe, A lifecycle page with a figure would enhance understanding toward backpack architecture and provide clarity to the sequence of all events & functions which are being called.

@tabacitu What do you say?

Totally! But not a page, I think a section inside our Operations page is more than enough. I'd put it right above the "Examples" here - https://backpackforlaravel.com/docs/5.x/crud-operations#examples-1
