Bug fix: The citrix-netsaler-syslog parser no longer fails on parsing JSON input

Adds new event.module and Cps.version fields

Removes the Product , msg and related.ip fields

Sets following tags: Cps.version , Vendor , ecs.version , event.dataset , event.kind , event.module , event.outcome , observer.type

Puts the CEF header fields under the Vendor.* prefix
