The patch makes IP address flush for external network
interface where IP address is assigned automatically
however an IP address from the same IP range is hardcoded in
the model.

Issue: First time you configure dpdk ovs switch it would stuck on
       answering salt-minion because kernel options, such as
       intel_iommu,iommu,isolcpus, are not set and ovs would
       exhaust all hugepages and fail to apply options on the fly.

Fix:   Configure ovs switch without waiting for an answer and
       reboot the node afterall as we do this all the time before
       starting automated pipeline.

non existent bridge.

By default, the alternative installed by `openvswitch-switch`
packages shadows (higher prio) `openvswitch-switch-dpdk` version,
e.g. for UCA Pike packages:

$ update-alternatives --query ovs-vswitchd
Alternative: /usr/lib/openvswitch-switch-dpdk/ovs-vswitchd-dpdk
Priority: 50
Alternative: /usr/lib/openvswitch-switch/ovs-vswitchd
Priority: 100

To avoid confusion, when DPDK is enabled and ovs-vswitchd-dpdk
should be used, remove the alternative for classic ovs-vswitchd
(which can easily be re-eneabled later if needed).

iteritems() was dropped in recent Python3 releases and items() is compatible
with Python 2.7.

When resolv.conf file is managed by salt, resolvconf service should be disabled
because it overwriting resolv.conf after reboot.

   * Wrong unicode character in the template leads to udev ignoring
     the rule completely
   * The template is unable to be rendered due to absent import
   * udev is not retrigerred with new rules

Currently when OVS-DPDK is enabled, instances fail to spawn
due to permissions mismatch, see nova bug for details:

Current logic does not apply n_rxq, pmd_rxq_affinity and mtu
for a dpdk port in case it is attached directly to a bridge
(not bonded).
This patch makes formula apply parameters in both cases.

This workaround is required until salt with the patch [1] is not
used.

- use 'ifenslave' tool to enslave necessary interfaces only if bond
  interface has been changed
- install package that provides 'ifenslave' tool

Non-destructive patch, won't affect anything because this
option is not used in any model yet.

Official guide for network.managed state provides an example:
bond0:
  network.managed:
    - type: bond
    - slaves: eth2 eth3
    - require:
      - network: eth2
      - network: eth3
    ...
without parameter: '- use:'

* add a new option 'require_interfaces' that allows to set
  '- require:' not only for 'bridge' interfaces
* using 'require_interfaces' allows to fix the order for states
  that create bonds (do not try to create bond0 before slave
  interfaces are configured!)
* using 'require_interfaces' allows to fix the order for states
  that create VLANs (do not try to create tagged interfaces before
  parent interface is created, it locks the parent interface
  creation!), example: bond0.2516 created before bond0
* using 'require_interfaces' allows to fix the order for states
  that depend on OVS interfaces

Parameter purge_hosts will enforce whole /etc/hosts file, removing entries
that are not defined in model except defaults for both IPv4 and IPv6 localhost
and hostname + fqdn.

It's good to use this option if you want to ensure /etc/hosts is always in a
clean state however it's not enabled by default for safety.
