ironic DevStack plugin fails to install on Ubuntu 16.04

[Pavlo Shchelokovskyy]

this is due to the package "openvswitch-datapath-dkms" is hardcoded as plugin dependency [1]

according to [2] it is not needed for kernels >= 3.13, so it is only needed for Ubuntu < 14.04, although it is present in upstream trusty repos.

The problem is this package is completely absent from upstream xenial repos (currently 4.4 kernel), so installing Ironic on 16.04 fails early on package installation step.

I'm not sure if devstack still officially supports ubuntu < 14.04, that is whether we can remove this package from the dependencies completely. And as xenial support in devstack is not there yet officially AFAIK, feel free to set Low priority for this bug.

I think 16.04 support is pretty important. To be honest, I'm not sure why we're installing stuff that neutron depends on, maybe we should leave it up to neutron's devstack plugin.

    remove neutron stuff from devstack deb packages

    It seems we are enforcing certain dependencies to be always installed on
    behalf of other projects. The issue I'm facing is we unconditionally
    install openvswitch-datapath-dkms which isn't necessary for Ubuntu kernels
    >= 3.13. Even worse, this package isn't available on Ubuntu 16.4 LTS thus
    breaking devstack setup.sh on that platform.

    This patch removes Neutron dependencies as those are handled by devstack[1]
    and devstack neutron plugin[2]

Reason: Abandoning this, @Pavlo (or anyone else) feel free to revive this. I was providing this as a help for devananda to try 16.04 but I have no working platform for trying it out.
