Admins can't see all domains in domain-list

[Sam Morrison]

When doing a "designate domain-list" as an admin I only see the domains I own. Need an all-tenants flag like nova to be able to see them all

The necessary plumbing for this has already been implemented, we just need to expose it via the API and update the client with an --all-tenants flag.

@AllenGuo - If you still plan on implementing this, please assign it back to yourself :)

    Enable X-Auth-Project flag in HTTP headers

    This also enables adding all_projects=true as part of the query string

    This will set the "all_tenants" flag in the context, and does a policy
    check to ensure the all_tenants is authorised
