Depends on #2994

This replaces the AbstractWatchService with a new WatchService interface and implementation that can be consumed as OSGi service. It makes use of a library that does a lot of what we currently do (hashing, removing duplicate events) and also implements a native watch service on MacOS which decreases response time to file changes.

@wborn Since we discussed this issue in the past, WDYT about the design?

@J-N-K What is the state here? I mean how much finished is this one?

Code-wise complete, but I'm pretty sure there are some minor tweaks needed.

One of the minor tweaks is to fix this test:

TEST org.openhab.core.model.core.internal.folder.FolderObserverTest#testModification()

I refactored it to a unit test. We want to test the FolderObserver, not the WatchService. It's clearly a timing issue, as it sometimes occurs, sometimes not and never on my local builds.

It looks good in general! 👍
I do already have a few minor review comments. 🙂

Why remove @Override if it still overrides the parent method?

I have removed the methods, the activate/deactivate methods are called automatically.
