Root cause: Due to a bunch of redis restarts, the bull-queues got unregistered and did not register again.
Solution: On every reconnect, readd the bull queue again.

Root cause: Express automatically redirected, fastify does not
Solution: Manually do the redirect

This commit contains a fixup for the original commit 64f2780a

Cache lookups will immediately register a promise to prevent multiple requests for the same ressource

Root cause: If multiple connections are opened at the same time after an update, the ui-middleware will do multiple requests to get initial data. That went especially worse, when e2e-tests are launched against ui-middlewares with multiple clients connecting at the same time.
Soltion: Make sure, that a node already caches stuff without a response.

Root cause: configuration was only reloaded on those nodes, that did the version update. The other nodes might not notice that.
Solution: On propagated version changes, the nodes always check for config changes

Root cause: cache keys handled differently when reading/writing
Solution: make sure keys are handled equally

Fixes OXUIB-1528

Use redirect instead of delivering index.html to prevent /ui paths in the future

Root cause: There are middlewares, which still use old redirects to /ui
Solution: To prevent 404s, we just serve the index.html

Solution: Only use the hash of the version

Root cause: Version has was updated before file cache
Solution: Keep all updates in one place and switch to new version at the same time

Fixes #6
