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
