YARN-11823: add new endpoints for getting jstacks of application and nodes

[Hean-Chhinling]

Description of PR

Add two new endpoints to ease the process of collecting JStack for running Application and Node.

1. {rm_address}/ws/v1/node/apps/{app_id}/jstack
2. {nm_address}/ws/v1/node/jstack

How was this patch tested?

Manually tested.
Will implement a unit test later

For code changes:

• Does the title or this PR starts with the corresponding JIRA issue id (e.g. 'HADOOP-17799. Your PR title ...')?
• Object storage: have the integration tests been executed and the endpoint declared according to the connector-specific documentation?
• If adding new dependencies to the code, are these dependencies licensed in a way that is compatible for inclusion under ASF 2.0?
• If applicable, have you updated the LICENSE, LICENSE-binary, NOTICE-binary files?
