This new allocator keeps the used space in memory and loads the database only on startup. If it allocates but something errors before it gets saved to the database, then thats fine because it will be cleared on next restart. This should resolve races between ip allocation with postgres and as a side effect should make it easier to implement random allocation instead of serial if we so desire.

This commit removes the old IP allocation logic which means that we no longer need to pass IP Prefixes all around the place, this allowed us to clean up some quite racy database code and addresses are now allocated before interacting with the database and fetched before registering the machines.

This PR adds a new IP allocator which should be more efficient, stable and less racy. This was necessary to deal with a discovered race condition in the allocation after adding postgresql integration tests.
I believe this is replacing the first "real" code I contributed to the project, and man, that was ver much needed 😆.
In addition it adds a new option to the integration tests to run them against postgresql instead of sqlite to ensure we do not have this regression again.
The last commit is the generation of new gh actions jobs and can be ignored as generated.
Fixes #1755
