docs: Execute the put on HBase, invoking the putModifier before executing the put
  if putModifier is not null.
  
  Any PutModifers registered with registerPutModifier will be invoked after
  the putModifier passed to this method is invoked, and before the Put is
  executed.
  
  @param putAction
  The PutAction to execute on HBase.
  @param putActionModifier
  Invoked before the Put to give callers a chance to modify the Put
  before it is executed.
  @return True if the put succeeded, False if the put failed due to update
