### Description of PR
JIRA: MAPREDUCE-7541. Fix AM WebUI attempts page.
Fix the MapReduce AM attempts page by binding `App` in request scope, so the
controller and view share the job selected for the current request.
This continues https://github.com/apache/hadoop/pull/8652 and preserves the
original author's commit. The follow-up addresses the outstanding cleanup
review and strengthens the HTTP regression test:
- Verify actual map and reduce attempt IDs and task-type filtering.
- Set connection and read timeouts.
- Disconnect HTTP connections and stop both the client service and MRApp in
finally blocks.
### How was this patch tested?
Tested with Java 17, without the native profile:
`mvn -pl
hadoop-mapreduce-project/hadoop-mapreduce-client/hadoop-mapreduce-client-app
-Dtest=TestAMWebApp,TestAppController -Dmaven.test.failure.ignore=false test`
- 28 tests passed, with 0 failures, 0 errors, and 0 skipped.
