Reduce cardinality of histogram type metrics

[cbankston-alk]

We'd like a way to disable the path, status, and method labels from being included on all histogram type metrics.

We've run into rate limits and cost problems due to the high cardinality of these metrics and are having to drop them. We'd prefer to keep these metrics around to help with future investigations.

We currently do not have the ability to roll up these metrics ourselves. The more efficient implementation is to remove them from the ingress-nginx metrics.

This is similar to https://github.com/kubernetes/ingress-nginx/issues/4972
