[FLINK-5150] [webui] Store metrics in sessionStorage
This PR modifies the webfrontend to no longer store the metrics setup
(selected metrics + their values) in localStorage but sessionStorage instead.
Using localStorage means that data is never deleted unless explicitly told.
It survives moving across pages, but also browser restarts. We currently lack
an automatic explicit removal, which was problematic since metrics for previous
jobs (that may even have been executed on a completely different cluster) were
still being updated. For example, if i ran any job on my local machine it would
fire 30+ requests regularly for dead metrics.
By moving to sessionStorage this issue is solved since the data is cleared
when the page is closed. However, you can still navigate to other pages and the
setup will survive. As a bonus you can now have 2 tabs for the same task with
different metric setups!
