Enable nstat input plugin for softnet_stat data 

Since we added to nstat's telegraf plugin the possibility
to collect data from `/proc/net/softnet_stat` regarding
dropped packets and rx_net_action a.k.a time squeeze, we need to enable
it globally on all hosts.

Also grafana dashboard update to include new graphs + added four
new Prometheus alers.
