Fix Health indicator/partition leader issues

Browse Source 
* Fix health indicator to properly indicate partition failure
 * Add new flag to control binder health indicator behavior
 * Regardless of the consumer that is reading from a partition, if the binder
   detects that a partition for the topic is without a leader, mark the binder
   health as DOWN (if the flag is set to true).
 * Remove synchronize block since only one thread executes the block
 * Add Docs for the new binder flag
 * Fix checkstyle issues
