RE logging - we can replace the backend logger from log4j to logback by:
* override `etc/startup.properties` replacing `pax-logging-service` for
`pax-logging-logback`
* in `org.ops4j.pax.logging.cfg` replace with
`org.ops4j.pax.logging.logback.config.file=${karaf.base}/etc/logback.xml`
* add `logback.xml` to dist
* add `pax-logging-logback` as a dependency in the pom so it gets
included in the dist
BUT then we need to put any of the included files from `logback.xml` in the
etc folder. Jars containing overrides will be ignored. Might be possible to
have the defaults (i.e. logback-includes) in a bundle by making it an extension
to pax-logging, but needs to be confirmed.
SO do we really need it? Why not go with log4j other than familiarity with
logback.
