This Improves the frontend performance with stale while
revalidate pattern.
There are noticeable performance problems in the frontend that
needed addressing. While implementing the stale-while-revalidate
pattern to display cached responses while re-fetching up-to-date
data in the background, in the same vein we used the opportunity
to remove legacy code involving redux as much as possible,
cleaned up many components and converted them to functional
react components.

This commit tackles the following issue:
When the release feed takes a long time to read (however), the former
solution would propagete requests to the SCM-Manager to multiple
requests of the specified feed url. This can, in the worst case, cause
a drain of resources like request threads.
We fix this with two actions:
1. We wrap the request itself in an executor with a timeout,
2. We only trigger one request at a time, so that we will not flood
the feed server with requests.
