[infinispan-dev] Removal of auto-detection of indexed entities

[Adrian Nistor]

BTW, these changes were added a bit late in the Infinispan 8.2 
development so I had to keep them at the minimum, otherwise I would have 
added lazy search factory initialization already.
But since we already have some strange random mystery deadlocks at 
server start (which do not seem related, until I'm proven wrong :)) I 
was reluctant to do it.
