[issue15502] Meta path finders and path entry finders are different, but share an ABC

[Nick Coghlan]

Nick Coghlan added the comment:

Specifically, what I did was to drop "find_module" from the Finder ABC, but keep the ABC itself as a way to document the common "invalidate_caches" API. The ABC definition no longer cares whether you implement find_module() or not. MetaPathFinder then enforces find_module(), while PathEntryFinder enforces find_loader().
