Use the same vallina Spark's metric name for corresponding metric

Currently Auron is using completely different metric name from the vallina spark for the same metric, take the following two snapshots as an example:

Vallina:

Native:

Here vallina has "sort time total", it corresponds to "Native.elapsed_time total"? (not sure)

Using different name for the same metric makes the comparison difficult, especially if there are some tools that using the metric names to extract the metric and evaluate a plan. It might require the tools to be rewritten.

For end user, they have to learn a new set of metric names, although it is not that difficult, but they have to learn.

And lastly for the necessity, since these metrics are already in a operator named NativeXxx, we don't need to use different metric names to differentiate between vallina metrics and native metrics?
