HBASE-18960 A few bug fixes and minor improvements around batchMutate 

* batch validation and preparation is done before we start iterating over operations for writes
* durability, familyCellMaps and observedExceptions are batch wide and are now sotred in BatchOperation,
  as a result durability is consistent across all operations in a batch
* for all operations done by preBatchMutate() CP hook, operation status is updated to success
* doWALAppend() is modified to habdle replay and is used from doMiniBatchMutate()
* minor improvements
