------------------------
Description:

code executed in stage is same.Stage-Isolated JVM profile analysis is easier to
locate problems.
# Support stage-level Isolated profile files
Or, we can support start Executor JVM profile from UI.

Different stages execute different codes, and hot spots will be ignored. Task
code executed in stage is same.Stage-Isolated JVM profile analysis is easier to
locate problems.And the entire Executor profile is not necessary, we can sample
it.
# Support stage-level Isolated profile files
# Support partial Executor profile sampling
Or, we can support start Executor JVM profile from UI.
