manubulon ipv6 support

[m4rcu5]

Describe the bug

When trying to use the manubulon snmp-interface command on a IPv6 host, the command will error out that is it unable to "Unable to resolve the UDP/IPv4 address".
The command seems to use the ipv4-or-ipv6 macro, correctly setting the -H parameter. However the --protocol parameter remains unchanged.

--protocol=PROTOCOL
   Network protocol to be used
   ['udp/ipv4'] : UDP over IPv4
    'udp/ipv6'  : UDP over IPv6
    'tcp/ipv4'  : TCP over IPv4
    'tcp/ipv6'  : TCP over IPv6

This seems to be true for all the manubulon plugins.

Expected behavior

The command should either switch the protocol argument according to the address used, or allow for a way to let the user set the protocol.

Thanks for creating this issue!

I have proposed changes in #10791 and would kindly ask you to verify if this works for you.

Thanks! I have patched my local command-plugins-manubulon.conf file and this works like a charm for both v4 and v6 hosts.

I saw you are also touching the documentation; I noticed that the ITL docs list snmp_warn and snmp_crit on the interface check both as optional and don't mention any defaults whereas the config does have some defaults set

	vars.snmp_warn = "300,400"
	vars.snmp_crit = "0,600"
