CI: Tests

[joe-getcouragenow]

Because we soon will have the DB, we should exercise it on each CI PR.

sys-core db has a basic test which is good, so since we now have state we should also:

go bench
go race

should we add cover too ? We have pretty bad in having many tests, but at least we are off to a good start at he DB level.

Load testing via GRPC should be added too once GRPC code stabilises.
Because authz is enforced might need a dummy user or way to tell sys-core to NOT enforce authz

Maybe add a GRPC load test too ?
