Since #YARN-3813/2.9.0/3.0.0, YARN supports ApplicationTimeouts. It helps
enforce lifetime application SLAs. Currently, lifetime indicates the overall
time spent by an application in YARN. It is calculated from its submit time to
finish time, including running time and the waiting time for resource
allocation.
YARN allows admins to set lifetime of an application at leaf-queue. It also
allows users to set it programmatically. During application submission, user
can set it in
`ApplicationSubmissionContext#setApplicationTimeouts(Map<ApplicationTimeoutType,
Long> applicationTimeouts)`.
So far, YARN supports for one timeout type - LIFETIME.
In this PR, we `setApplicationTimeouts` when the YARN dependency is
available, e.g. the default Hadoop 3.3 or user-specified Hadoop 2.9+ when
Hadoop is provided at compile phase.
### Why are the changes needed?
<!--
Please clarify why the changes are needed. For instance,
1. If you propose a new API, clarify the use case for a new API.
2. If you fix a bug, you can clarify why it is a bug.
-->
This can enforce the application SLAs.
For example, when the YARN queue is hit its limits of app concurrency or
cpu/mem, an app will be pending for a very long time or even 'forever' at
ACCEPTED doing nothing.
Sometimes, users also may want their app to succeed or timeout/failed with
proper time constraint.
### Does this PR introduce _any_ user-facing change?
<!--
Note that it means *any* user-facing change including all aspects such as
the documentation fix.
If yes, please clarify the previous behavior and the change this PR proposes
- provide the console output, description and/or an example to show the
behavior difference if possible.
If possible, please also clarify if this is a user-facing change compared to
the released Spark versions or within the unreleased branches such as master.
If no, write 'No'.
-->
yes, we add a new conf but do not change the current behavior
### How was this patch tested?
<!--
If tests were added, say they were added here. Please make sure to add some
test cases that check the changes thoroughly including negative and positive
cases if possible.
If it was tested in a way different from regular unit tests, please clarify
