Added v3 domain env variables

The current authfile class does not currently specify domains
and if someone is using v3 api, it will fail with messages
about a domain not being specified. This change exposes two new
parameters to specify domain for project and user that are both
defaulted to false. When they're specified they will add two
env vars in openrc.
