Adds endpoints for SJC01, HKG02, LON02, TOR01, MEL01, PAR01
The way the endpoints map is constructed is now a bit simpler;
rather than explicitly specifying a dict for every single one,
the appropriate dict is created for each datacenter specified in
object_storage.consts and included in the ENDPOINTS constant.
Not explicitly spelling out every DC's two endpoints (private and
public) just so happens to save us some PEP-8 complaints due to
lines >=80 chars.
