Start an ebay oauth connect
Return the eBay connect URL plus the state handle for this attempt. Returns 400 if the platform eBay app is not configured for this environment. A multi-org credential must send an Organization-Id, Connection-Id or Entity-Id selector, or gets a 400. Call this from a browser with credentials (cookies) included: the callback that finishes the connect is bound to the session cookie this response sets, so it only completes for the same browser. Returns 409 if this browser already has another organization's eBay connect in progress.
