[Observium] $config['snmp']['max-rep'] working?

Hi Chaps,

I'm trying to use $config['snmp']['max-rep] = 9 to work around an issue with a device that won't return everything from ifAlias when using the default (10), however checking the discovery debug it doesn't actually seem to actually be setting the -Cr option in snmpbulkwalk? Am I missing something else to make this work, or is it actually just not working due to its 'experimental' state in the documentation?

Running 0.15.10.7059

Thanks, Tim C
