Allow for customizing the labels included in the final end_to_end_duration_seconds histogram, allowing multiple probs to be deployed and the latency split by labels forwarded to it from AlertManager.

We're using e2ealerting across our k8s fleet to monitor latency from ingestor to AM and want to be able to break that down by specific tags like cluster name or AZ. We could solve this by generating one rule for each but this becomes harder to manage as our cluster grows automatically. Instead this adds the ability to pass through custom labels from AM to the histogram and improves the timestamp seen logic to track this by the particular facets.
This adds 2 configuration parameters:
receiver.labels-to-track: This controls the label values of a metric that the "seen timestamp" will differentiate. This is useful if you want to track a different timestamp per hostreceiver.labels-to-forward: This controls the labels that will be forwarded from the AM payload to the histogram metric. Useful to break the histogram down by cluster or region.
