not able to use SNMP 1/2c/3 on same command

[joschi99]

I would like to configure the commands for the plugin for all SNMP versions. I can add the options "--username" or "--authpassword" without any problem and the plugin works correctly even on SNMP 1/2c, but if I add the option "--privprotocol" I got the error:
Option privprotocol requires an argument

If I add an option for privprotocol like "--privprotocol=aes", then I got the error:
CRITICAL - cannot create session object: An empty userName was specified
on SNMP 1/2c

Could you change the behavior to allow 1 command for all SNMP versions?
