* Rename serverkeyapi to signingkeyserver
We use "api" for public facing stuff and "server" for internal stuff.
As the server key API is internal only, we call it 'signing key server',
which also clarifies the type of key (as opposed to TLS keys, E2E keys, etc)
* Convert docker/scripts to use signing-key-server
* Rename missed bits
* More key tweaks
* Start testing stuff
* Move responsibility for generating local keys into server key API, don't register prom in caches unless needed, start tests
* Don't store our own keys in the database
* Don't store our own keys in the database
* Don't run tests for now
* Tweak caching behaviour, update tests
* Update comments, add fixes from forward-merge
* Debug logging

* Perform final comparison against original set of requests
