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.

Leave bond_status.interfaces undefined to disable (default).

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.

Change-Id: I3595fd0b8cab06215c620642da69dd29c398396a

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.

This reverts commit a63f4053f3.

The support for collecting syslog is going to be moved to the rsyslog
formula.

This commit adds more built-in alarms to the Linux formula.
