 Warn while building Nakamura - Instructions in Export-Package ...
KERN-2905 Refactoring and consolidating similar searches into new Solr search design.

Searches refactored:

The following were consolidated into one 'role.json' search and deprecated (they still exist):

/var/search/pool/me/manager.json
/var/search/pool/me/manager-all.json
/var/search/pool/me/viewer.json
/var/search/pool/me/viewer-all.json

These searches are now backed by MeQueryHandler.java

/var/search/pool/auth-all.json is now handled by MyLibraryQueryHandler and shares much of the functionality of the 'Me' content queries.
KERN-2905 Deleting some classes that are now unused.
KERN-2905 Improve Javadoc documentation of new classes.
KERN-2905 Addressing PR review comments ...

* Renaming 'MeQueryHandler' to 'AccessScopedContentQueryHandler', and renaming the string representation 'Me' to be the exact same as the class name.

* Renaming "MyLibraryQueryHandler" to LibraryContentQueryHandler, to reflect that it is not always "my" library

* Pushing some more logic down into AbstractContentSearchQueryHandler as it is more generic than I thought

* refineQString now just returns a String, instead of appends to a StringBuilder whose state is unknown.

* Only use _q in the JSON search endpoint stub auth-all.json. Push the logic for more complex query building into the buildCustomQString method
