Adopt oslo incubator

[Salvatore Orlando]

for i18n and loopingcall vmware-nsx relies on neutron.
This might cause unexpected failures as these dependencies might be updated without notice.

vmware-nsx should import modules directly from openstack.common rather than using neutron as an intermediary

    Adopt oslo incubator

    This patch removes usage of incubated libraries from
    neutron.openstack.common and starts "copying" such libraries from
    the oslo incubator as any other project.

    As vmware-nsx currently only uses i18n, and loopingcall, these are
    the only modules added to openstack-common.conf
    All the imports pointing out to neutron.i18n or
    neutron.openstack.common.loopingcall are amended in this patch.
