Cache Utils group_work

2.4

• Use a different logger per event type
• Improved the wording of the logs
• Add the used log level to the string output of a listener

2.3

• Switch the configuration from an array of String to a String with a separator, as a workaround to a bug with the replication of the configuration over the cluster

2.2

• Embed an empty config file to be created in karaf/etc/ to avoid a synchronization issue with Cellar on clustered environments
• Do not register a listener configured for invalid events

2.1

• Implemented a cache listener to log the cache events
• Added the possibility to disable the cache dependencies listener (disabled by default)
