"""The SNMP agent through napalm-device-types' configure_snmp_agent (netOrk #1105).

fix_snmp hard-coded community "public". The switch's agent is built in and the
switch filters nothing for its own management plane, so of the template's steps
only "configure" (community, contact, location) and "start" (save, verify) do
work here; the caller's values are used as given.
