-----------------------------------------------------------------

I was going to push this as default in hbase-2.4 and on hbase3 in the morning unless objections. I've been running it a while and its nice... There is a procedure per WAL split and ServerCrashProcedure doesn't block and wait till ALL WALs split before it can move forward; now it schedules all the WAL splits and then suspends itself freeing up the ProcedureExecutor to do other work.

> Means changing this value in HConstants to false:
>    public static final boolean DEFAULT_HBASE_SPLIT_COORDINATED_BY_ZK = true;
> Should probably also deprecate the current zk distributed split too so we can clear out those classes to.
