[davesh0812]

Implements - ML-6259.

1. Implements ModelMonitoringApplicationBaseV2 :
   a. with new do_tracing signature.
   b. delete self.context and uses the monitoring_context param as mlrun context.
2. Implements MonitoringApplicationContext - The monitoring context holds all the relevant information for the monitoring application, and also it can be used for logging artifacts and results.
3. Implements EvidentlyModelMonitoringApplicationBaseV2.
4. Add __PrepareMonitoringEvent step the application serving graph - preparing the application event for the application step.
5. Update _PushToWriter step.
6. Update HistogramDataDriftApplication to v2.
7. Change ModelMonitoringWriter and ModelMonitoringWriter._reconstruct_event to work with 2 kinds of events - metric and result, for now the ModelMonitoringWriter writes only the results to the databases.
8. Change the applications (regular and evidently) and the result object directories.

Nice work!

I had a few comments about the docs, tests, and implementation.
