Motivation
Enable by default, and allow to configure, the sticky reads feature in BK client, which will force to direct all the read requests for a particular ledger to be issued (by preference) against a single bookie, to better exploit read-ahead caching.
See apache/bookkeeper#1808 for a more in-depth discussion on this.
