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

fix_snmp hard-coded community "public" and sent the config-mode command through
_send_command, which waits for the exec prompt and so ran into its timeout in
config mode (#6). The caller's values go through _apply_config_lines now, which
waits for any prompt and reports a rejected line.
