Hazelcast webfilter could not be found WARN messages

Since Stash 3.4.1, the logs are spammed with hazelcast WARN messages such as this:

com.hazelcast.web.SessionListener The com.hazelcast.web.WebFilter could not be found. com.hazelcast.web.SessionListener should be paired with a com.hazelcast.web.WebFilter.

This has made troubleshooting logs more difficult as logs get very huge.

Temporary workaround is to add the following to stash-config.properties and restart Stash:
logging.logger.com.hazelcast.web.SessionListener=ERROR
