[FLINK-8605] [rest] Enable job cancellation from the web UI
## What is the purpose of the change
In order to support the job cancellation from the web UI, including when using
Yarn, we have to register the JobTerminationHandler under /jobs/:jobid/yarn-cancel
and /jobs/:jobid/yarn-stop. This is just a temporary fix until we can send
arbitrary REST verbs through the Yarn proxy.
## Brief change log
- Introduce `YarnCancelJobTerminationHeaders`
- Introduce `YarnStopJobTerminationHeaders`
- Register `JobTerminationHandler` with default `TerminationMode#CANCEL` under `YarnCancelJobTerminationHeaders`
- Register `JobTerminationHandler` with default `TerminationMode#STOP` under `YarnStopJobTerminationHeaders`
## Verifying this change
- Added `YarnCancelJobTerminationHeadersTest` and `YarnStopJobTerminationHeadersTest`
- Tested manually
## Does this pull request potentially affect one of the following parts:
- Dependencies (does it add or upgrade a dependency): (no)
- The public API, i.e., is any changed class annotated with `@Public(Evolving)`: (no)
- The serializers: (no)
- The runtime per-record code paths (performance sensitive): (no)
- Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Yarn/Mesos, ZooKeeper: (no)
- The S3 file system connector: (no)
## Documentation
- Does this pull request introduce a new feature? (no)
- If yes, how is the feature documented? (not applicable)
