Current thresholds don't matche real warning/minor values for
the time_squeeze numbers. As a result we have false positive.

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.

The other disk alerts use predict_linear() to trigger before a disk gets
full but they don't trigger when the disk is effectively (or nearly)
full.

Since metrics on dropped packets are counters, the alerts should use
the rate() function. This change also fixes some inconsistencies in the
alert descriptions.

This change adds the Telegraf configuration to collect swap metrics, the
associated Prometheus alarms and graphs to the Grafana dashboard.
