Hi,

I tried to use the following expression in keycloak.conf:
log-level=${ROOT_LOGLEVEL:INFO}

I wanted to use the env var ROOT_LOGLEVEL to set the root log level to DEBUG, but this doesn't work, because for keycloak.conf only system properties are resolved. The same expression for another logger works in quarkus.properties.

I'm wondering whether it makes sense to support the same expressions in keycloak.conf as it is done for quarkus.properties?
