[collectd] SNMP plugins multiple threads

[Domagoj Mikac]

collectd-snmp man page says that SNMP plugin uses up to maximum of 10
threads. 

For large configurations, when pooling thousands of variables, 10
threads might not be enough to finish all the pooling in predefined
cycle (in my case interval is set to 300 sec (5 minutes)). 

My question is: Is there a way to increase the number of threads for
SNMP plugin ?
