This change removes dns events from the network connection category. The
one change is that sysmon_regsvr32_network_activity.yml needs to test
the network connection category separately from the DNS event id.
- Added log source rewriting
- Removed log source merging condition type setting
- Simplified SigmaLogsourceConfiguration constructor
- Condition is generated in SigmaParser instead of SigmaLogsourceConfiguration
Missing:
- Merging of raw config dict for backends that rely on this (es-dsl)
