Run IIS experiments by relying on spark 3.4 version

[marekhorst]

This task is related to running a subset of IIS modules currently written in spark 2.4 on the newly available spark 3.4 version.

This may require:

• altering oozie workflow definition by specifying a new sharelib name and defining other spark related configuration parameters such as app/query listeners, history server address, event log directory etc
• changing dependencies
• new version of spark-utils: 2.11 will have to be released, compatible with scala 2.12: https://github.com/CeON/spark-utils/issues/16
• altering java code
• dropping iis-common scala sources which are difficult to maintain (and results in false positive errors indicated by the Eclipse IDE) and replacing those simple utility classes with java equivalents
