[FLINK-2989] job cancel button doesn't work on YARN
In addition to the REST-compliant "DELETE /jobs/<jobid>", allows
cancellation also via a special GET request of the form
"GET /jobs/<jobid>/yarn-cancel".
That enables us to cancel jobs from the web frontend on YARN while
keeping a REST-compliant DELETE alternative.

> Project: Flink
> Issue Type: Bug
> Components: Webfrontend
> Reporter: Sachin Goel
>
> The newly added Cancel button doesn't work on Yarn, when accessing via Yarn
> Web Application proxy. It works fine when we're directly on the web monitor.
> The reason is Yarn doesn't allow DELETE requests to the AM yet. It should be
> enabled in 2.8.0. [YARN-2031, YARN-2084.]
> A workaround for now can be to use a {{GET}} method instead of {{DELETE}},
> but that breaks the conventions of REST.
