prepend hardcoded string value to origin.hostname structured data

[kortemik]

add configuration variable

prefixOrigin = "myGroup/"

so it becomes

[origin@48577 hostname="myGroup/$hostname/$containerId"]

[StrongestNumber9]

I'd split these to different entities entirely, more like [origin@48577 group="myGroup" hostname="$hostname" containerId="$containerId"]

[kortemik]

origin is already defined and in use, therefore we can not modify the schema. i propose that we add totally new key-value structure for transporting this kind of adhoc information
