Switching the project also switches the region

[Justin Pomeroy]

The following scenario can occur when there are multiple service region endpoints and multiple projects:

1. Login using initial region
2. Switch to a different region
3. Switch to a different project

The result of this is that the region is set back to the initial region that was used after logging in. I would expect that the region remains the same after switching the project.

There are currently two fixes out for this bug. The other one from Eric Peterson is here: https://review.openstack.org/#/c/119202. I think the only real difference is that Eric's fix saves the selected region in a cookie so that it sticks across sessions, whereas my fix linked above only persists the selected region when obtaining a new token, such as when switching projects. We'll need to decide which approach to use.

    Make region and project sticky

    This change will make the region and project "sticky" in that whatever is selected
    will remain selected. When users select other projects or login/logout the region will
    stay what the user last selected, and users will try to be returned to the last used
    project
