+Bugfix: Fix logging levels
+
+We've fixed the configuration of logging levels. Previously it was not possible
+to configure a service with a more or less verbose log level then all other services
+when running in the supervised / runtime mode `ocis server`.
+
+For example `OCIS_LOG_LEVEL=error PROXY_LOG_LEVEL=debug ocis server` did not configure
+error logging for all services except the proxy, which should be on debug logging. This is now fixed
+and working properly.
+
+Also we fixed the format of go-micro logs to always default to error level.
+Previously this was only ensured in the supervised / runtime mode.
