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.

On mirror.fuel-infra.org there is a package
td-agent-additional-plugins which ships all the additional
fluentd gems (plugins and its deps).

Its possible for fluentd to match and report false positives with
current regex for hdd errors. The following log example line:
failed to deactivate service binding for container
jenkins_slave02.1.tijvdstzxrs6gikbwrtu85078" error=
can be catched by the regex and report about the (false positive)
issue will be sent to prometheus. So the new regex must be more strict,
in order to avoid such alerts.

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.

This is typically used to mount Docker containers but it generates too
many volatile metrics which aren't useful.

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.

The `linux_netlink.ls` function used a regex to choose which interfaces
to collect metric for.
`_alphanum_re = re.compile(r'^[a-z0-9]+$')`
Unfortunately, by default this excludes vlan and tap interfaces, which
are kind of important. ie `bond0.120` or `tap2a3dab86-fb`.
We also have a problem where even if we update the regex to include
these interfaces... if someone deletes and spawns a new instance then
the tap device name changes on the compute host, which will not be
monitored unless someone re-runs the `collectd` on the compute again.
Less than ideal.
This commit lets us choose `VerboseInterface "all"` using Pillar data
to avoid this problem.
