gateway: expose the eight telemetry headers requested in co-op/support#39

Adds x-litellm-model-name, -call-id, -key-spend, -response-duration-ms, -overhead-duration-ms, -callback-duration-ms, -attempted-retries and -attempted-fallbacks to the CORS expose list, on the GM's go-ahead. Renames COST_HEADERS to EXPOSED_HEADERS since the list is no longer only costs. x-litellm-key-spend discloses the caller's own key spend, which is their own data; noted in the thread so it can be dropped if anyone objects.
