Support keystone V3 API

[Kyle Mestery]

The python-neutronclient has keystone V3 support as of Juno [1], it's unclear if we need to do anything for the server. Filing this bug to track this so we don't forget to address this during Mitaka.

Ihar, I don't think this needs an RFE tag according to my discussion with our PTL. Removing it for now unless Armando adds it back.

[Armando Migliaccio (armando-migliaccio)]

I am thinking that this should be treated as a regular bug. If Keystone v2 is being deprecated (or in the process to) it's best to get to v3 asap. I am not sure what conversation we'd need to have...it sounds like a no-brainer.

[Armando Migliaccio (armando-migliaccio)]

We'd need someone who can verify what's the current status and do the work.

I'm working on this, it turns out.

    Pull project out of request in addition to tenant

    Keystone V3 renamed tenant to project. In order to deal with keystone
    V3, start pulling X-Project-Id from the headers.

    Since keystonemiddleware authtoken sets both X-Project-* and
    X-Tenant-*, we don't need to look up X-Tenant-*.

    Don't do anything with renaming the internal variables - that will come
    later.
