Updated javadocs for ResourceChangeListener

> Clarify and complete removal resource events
> --------------------------------------------
>                 Key: SLING-6066
>                 URL: https://issues.apache.org/jira/browse/SLING-6066
>             Project: Sling
>          Issue Type: Improvement
>          Components: API, JCR, ResourceResolver
>            Reporter: Carsten Ziegeler
>             Fix For: JCR Resource 2.8.2, API 2.15.0, Resource Resolver 1.4.20
> As recently discussed in the mailing list, if a ResourceChangeListener is 
> interested in removal events, the listener might not get the event it is 
> interested in. For example, if the listener is registered with a glob 
> pattern, like **.jsp, but the parent (or any parent) of a jsp is removed. In 
> that case no removal event for the jsp itself is sent.  Which means the 
> listener is unaware of removals.
> We need to clarify this in the javadocs, but also should implement handling 
> removal in the following:
> If a listener is registered for removal events - regardless if a glob pattern 
> is used or not - the listener will be notified of removals of any parent node 
> up to the top level node. For example if a listener is interested in 
> /a/b/c/**/*.jsp, a removal of any resource below "c", but also removal of 
> "a", "b", or "c" is reported to the listener.
