docs: Execute the get on HBase, invoking the getModifier before executing the get
  if getModifier is not null.
  
  Any GetModifers registered with registerGetModifier will be invoked before
  the Get is executed, and after the getModifier passed to this function are
  called.
  
  @param get
  The Get to execute.
  @param getModifier
  Invoked before the Get to give callers a chance to modify the Get
  before it is executed.
  @return Result returned from the Get.
