Linux bridges are automatically set UP when
any parent interface is UP.

But for OVS bridges it doesn't work.

For dpdk and non-dpdk bridges, always create a
config file in /etc/network/interfaces.u/ and
bring the bridge interface up after it is configured,
even if it doesn't have IP address.

Issue description:

  PXE interfaces, which are used by salt should not be restarted
during salt calls, otherwise communication between salt master and
salt minion would be interrupted.
  Therefore it is possible to specify "noifupdown: True" in pillars
for this interface or group of interfaces, which are used for PXE
network.
  This pillar structure will remain until one removes it manualy.
  It is not possible to remove it during deploy and enforce network
state without touching the model.

  It is possible to override pillars from CLI like:
  # salt ctl01* state.apply linux.network.interface \
    pillar='{"linux":{"network":{"interface":{"ens3":{"noifupdown":True}}}}}'

  However it is not easy/possible to predict all interfaces for PXE
network.

Solution:
  Provide global noifupdown pillar value check.
  If it exists, noifupdown will take effect and not otherwise.
  So our deployment would have next steps:
  - Execute: linux.network.interface pillar='{"linux":{"network":{"noifupdown":True}}}'
  - Reboot node to enable kernel params like hugepages etc.
  - Execute: linux.network.interface with no params to ensure PXE.

Pipelines may pass this parameter to control noifupdown behavior.

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.

Previously there were no dependency and as result we tried to add port to
non existent bridge.

Previously, setting up routes did not allow passing 'require_reboot',
so each route change would lead to a networking service restart,
rendering interface configuration options like 'noifupdown' useless.
Allow disabling network restart per-interface using the existing
'noifupdown' option.

Fixed:
   * The udev-rules template is not tested
   * 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

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

This patch adds dependency for ovs_port_up_{{ interface_name }} on
linux_interfaces_final_include. This is needed to avoid errors like
"Unknown interface XXX"

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}
```

We need to save our manualy managed interfaces to different directory to
workaround salt bug that causes interface deconfiguration in
/etc/network/interfaces for interfaces manualy configured in
/etc/network/interfaces.d

install each package, whereas "pkgs" makes just a single call so that it
