HBASE-24616 Remove BoundedRecoveredHFilesOutputSink dependency on a TableDescriptor (#1955) 

Purge query Master for table descriptors; make do w/ generic options.

Logging cleanup.

hbase-server/src/main/java/org/apache/hadoop/hbase/wal/BoundedRecoveredHFilesOutputSink.java
 Undo fetching Table Descriptor. Not reliably available at recovery time.
