Use non-shared indexes by default

Currently, query auto-config will create either shared or non-shared indexes depending on the cache mode.
Infinispan should provided the following default configuration for all cache modes:

• Index side: memory mapped local indexes stored on disk, opened with a Near Real Time index manager. Indexing will all be ASYNC, with the possibility of overriding as SYNC
• Query side: query will be broadcast by default

Furthermore, we will remove the Index.PRIMARY_OWNER, Index.ALL, etc configurations
