Add `es.inference.requests.time` metric around `infer` API. As recommended by OTel spec, errors are determined by the presence or absence of the `error.type` attribute in the metric. "error.type" will be the http status code (as a string) if it is available, otherwise it will be the name of the exception (e.g. NullPointerException). Additional notes: - ApmInferenceStats is merged into InferenceStats. Originally we planned to have multiple implementations, but now we're only using APM. - Request count is now always recorded, even when there are failures loading the endpoint configuration. - Added a hook in streaming for cancel messages, so we can close the metrics when a user cancels the stream. (cherry picked from commit 26870ef)
