Remove deprecated metrics

[bnjjj]

Metrics

• apollo_router_http_request_retry_total has been removed and will be supported now by http.client.request.duration metrics
  with the http.request.resend_count attribute which is automatically set when default_requirement_level is set to recommended.

• apollo_router_timeout has been removed. This metric conflated timed-out requests from client to the router, and requests from the router to subgraphs.
  Timed-out requests have HTTP status code 504. Use the http.response.status_code attribute on the http.server.request.duration metric to identify timed-out router requests,
  and the same attribute on the http.client.request.duration metric to identify timed-out subgraph requests.

• apollo_router_http_requests_total has been removed and replaced by http.server.request.duration metric for requests from clients to router and http.client.request.duration for requests from router to subgraphs.

• apollo_router_http_request_duration_seconds_bucket has been removed and replaced by http.server.request.duration metric for requests from clients to router and http.client.request.duration for requests from router to subgraphs.

• apollo_router_session_count_total has been removed and replaced by http.server.active_requests.
