[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
