Tests are now run through unix socket by default allowing
parallel execution. Test setup configuration is done via
environment variables instead of config files.
* secret-is-base64 -> jwt-secret-is-base64
* role-claim-key -> jwt-role-claim-key
* max-rows -> db-max-rows
* pre-request -> db-pre-request
* root-spec -> db-root-spec
* db-schema -> db-schemas
This is not a breaking change, because aliases are added as well.
refactor: sorted all config keys alphabetically where applicable
