Feature/191 multiple detector types breaking change v1

[stevanbz]

Description

Added multiple detector types as part of DetectorInput. Extended detector with new field: docLevelMonitorPerCategory used for storing the doc level category:monitorId pairs (used when detector is being updated in order to determine which monitors should be deleted and which query indices should be removed).

In order to support multiple detector types, detectorInput has been extended with List detectorTypes property. To keep the possibility of getting all alerts and findings per detector type and per detector id AlertsService and FindingsService has been extended to use the groupedListener and then they are joining/merging the search alert/finding results.

When updating the detector, if one of the doc level monitor has been deleted by deselecting rules, and the whole rule category has been removed, query index will also be deleted.

Here is the document describing the changes from the perspective of client
