rename project: ovirt-engine-hyper-upgrade to ovirt-fast-forward-upgrade

Verified that patches to gerrit are mirrored properly to https://github.com/oVirt/ovirt-fast-forward-upgrade so closing the request.

New project created:
https://gerrit.ovirt.org/#/admin/projects/ovirt-fast-forward-upgrade
Reviews can now be sent to it instead, I will rename the GitHub mirror as well and update sync settings

Renaming projects in Gerrit is not a trivial task so I'll just create a new empty project and copy over all the commits.
This shouldn't be a big deal since I don't see much review activity in the existing project anyway:
https://gerrit.ovirt.org/#/q/project:ovirt-engine-hyper-upgrade

we got a final approval on the ovirt-fast-forward-upgrade, can you move forward with the creation/move to the new project?

so which one should it be 'ovirt-engine-fast-forward-upgrade' or 'ovirt-fast-forward-upgrade'?
