* Update upstream OVS debian packaging to be on par with package
  source in Debian/Ubuntu:
  - Provide a openvswitch-switch-dpdk package that integrates with
    the dpdk package in the distributions so that end users can opt
    into a DPDK-enabled Open vSwitch binary.
  - Provide systemd service files.
  - Provide openvswitch-source package for reproducible integrated
    build of for example OVN.
  - Stop building shared library and subsequently remove
    libopenvswitch and libopenvswitch-dev binary packages.

The packaging source in the OVS repository has drifted away from
what is currently in Debian and Ubuntu.  This state is problematic
because from time to time someone tries to build packages from the
upstream OVS debian package source and then expect that package to
work with up-/down-grades from-/to/ distro versions.

To support the on-going work to remove the out of tree OVS kernel
driver from the repository [0], an update to the debian packaging
is also required.  On the back of the discussion in [0] we agreed
that replacing the current version with what Debian and Ubuntu
is currently converging on would be preferable.

This commit is a first in a series to update the upstream OVS
debian packaging source to be up to date with what is currently
in Debian and Ubuntu.

We've been warning about the change since 2.1, which was released a year
ago.

mininet uses the Open vSwitch controller by default, for testing.
