[SPARK-3777] Display "Executor ID" for Tasks in Stage page
Now the Stage page only displays "Executor"(host) for tasks. However, there
may be more than one Executors running in the same host. Currently, when some
task is hung, I only know the host of the faulty executor. Therefore I have to
check all executors in the host.
Adding "Executor ID" would be helpful to locate the faulty executor. Here
is the new page:
