HBASE-23221 Polish the WAL interface after HBASE-23181 (#774) 

Removes the closeRegion flag added by HBASE-23181 and instead
relies on reading meta WALEdit content. Modified how qualifier is
written when the meta WALEdit is for a RegionEventDescriptor
so the 'type' is added to the qualifer so can figure type
w/o having to deserialize protobuf value content: e.g.
HBASE::REGION_EVENT::REGION_CLOSE

Added doc on WALEdit and tried to formalize the 'meta' WALEdit
type and how it works. Needs complete redo in part as suggested
by HBASE-8457. Meantime, some doc and cleanup.

Also changed the LogRoller constructor to remove redundant param.
Because of constructor change, need to change also
TestFailedAppendAndSync, TestWALLockup, TestAsyncFSWAL &
WALPerformanceEvaluation.java

*
* <p>A particular WALEdit 'type' is the 'meta' type used to mark key operational
* events in the WAL such as compaction, flush, or region open. These meta types do not traverse
* hbase memstores. They are edits made by the hbase system rather than edit data submitted by
* clients. They only show in the WAL. These 'Meta' types have not been formally specified
* (or made into an explicit class type). They evolved organically. HBASE-8457 suggests codifying
* a WALEdit 'type' by adding a type field to WALEdit that gets serialized into the WAL. TODO.
* Would have to work on the consumption-side. Reading WALs on replay we seem to consume
* a Cell-at-a-time rather than by WALEdit. We are already in the below going out of our
* way to figure particular types -- e.g. if a compaction, replay, or close meta Marker -- during
* normal processing so would make sense to do this. Current system is an awkward marking of Cell
* columnfamily as {@link #METAFAMILY} and then setting qualifier based off meta edit type. For
* replay-time where we read Cell-at-a-time, there are utility methods below for figuring
* meta type. See also
* {@link #createBulkLoadEvent(RegionInfo, WALProtos.BulkLoadDescriptor)}, etc., for where we
* create meta WALEdit instances.</p>
*
* <p>WALEdit will accumulate a Set of all column family names referenced by the Cells
* {@link #add(Cell)}'d. This is an optimization. Usually when loading a WALEdit, we have the
* column family name to-hand.. just shove it into the WALEdit if available. Doing this, we can
* save on a parse of each Cell to figure column family down the line when we go to add the
* WALEdit to the WAL file. See the hand-off in FSWALEntry Constructor.
