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.

Revert "Adds ability to set mtu in reclass"

Adds ability to set mtu in reclass

Change of mtu is not handled by reclass. Example interface:
```
        br_ctl:
          enabled: true
          type: bridge
          proto: static
          mtu: 1450
          address: ${_param:single_address}
          gateway: ${_param:ctl_gateway}
          netmask: ${_param:control_network_netmask}
          use_interfaces:
          - ${_param:primary_first_nic}
```

This is required in order to use vfio-pci driver.

Currently when Salt starts setup-loopback-device service
systemd executes losetup command and even if it worked
successfully, systemd marks service as inactive(dead).
And Salt considers service as dead. In order to fix
this behavior, we need to add RemainAfterExit=true to
loopback systemd unit template.

change to apparmor config that will require this option.
