Implement a support for creating multiple values on the agent variable HostMetadataItem with a comma separation like static HostMetaData whith a ','. The fact of having to search only for the release of the OS, and not to combine it with a port, a particular service does not allow to properly industrialize the auto-registration in Zabbix.

HostMetaDataItem(s) = system.uname, system.run[/etc/script.sh], xxx

Using static HostMetadata multiplies the number of Zabbix configuration files.
