### Description
The Kemi framework supports `KSR.info()` and `KSR.warn()`, but the level in between is missing. Our legacy systems use INFO logging in our dev systems and NOTICE logging in production environment. So everytime we replace some legacy Kamailio config with Kemi code, we stumble upon then missing `KSR.notice()` method or the missing "notice" level parameter to `KSR.log()`.
