    Elevate context for router lookups during floating IP association.
    
    During a floating IP association, the tenant making the request
    may not always be the owner of the router.  To make the association,
    Neutron needs to query the router details internally but needs to
    use an elevated context to do so.  Otherwise, the user sees a
    cryptic error stating that the router doesn't exist.
