XD-106 Improve Logging when container starts/stops

* Provide better MANIFEST.MF generation
  - E.g. store the version number
* Add Spring Shell dependency
* Add dependency `org.apache.tomcat:tomcat-jsp-api` to reduce several bogus logging warnings
* Provide some basic ASCII art
* While normal logging level is WARN, set the logging level for `RedisContainerEventListener` to INFO
