Tune logging formats and rotating

Recreate the opencell+keycloak docker image via a Dockerfile and creating new wildfly config via the its cli. This breaks down to:

• Upload rendered templates for logger.cli and Dockerfile
• Update docker-compose up to make it rebuild always the custom image
• Rotate server.log by size not by date
• Keep access.log rotating by date as it's not expected to grow and it's useful to have accesses by date
• Make server.log and opencell-debug.log rotate with same size criteria (add variables)

Also, taking advantatge of the situation, make things prettier for promtail/grafana/loki

• Change existing formatters so that
  • they have both the date, not only the time
  • they separate milliseconds with '.'. This is useful for promtail to parse timestamps. Golang can't do it with a ','
