Batch raw OID retrieval to bypass 'tooBig' SNMP error

When trying to poll about 40 OIDs at the same time we got
an SNMP 'tooBig' error and no stats were exported at all.
One can change the size limit in the server's SNMP configuration
but it can be done only so much.
This is a bit naive approach to fix it which seems to be working.
Can you rename this variable while you're at it ? We shouldn't override python function names: https://docs.python.org/2/library/functions.html?highlight=object#object

Thanks!
