[FLINK-9027] [web] Clean up web UI resources by installing shut down hook
## What is the purpose of the change
The RestServerEndpoint creates temp directories to upload files and store
the web ui.
In case of a hard shut down, as it happens with bin/stop-cluster.sh we
should still
delete these files. We do this by installing a shut down hook.
