Description

Currently the /metrics/snapshot endpoint in libprocess has a hard-coded rate limit of 2 requests per second:

  MetricsProcess()
    : ProcessBase("metrics"),
      limiter(2, Seconds(1)) {}

This should be configurable via a libprocess environment variable so that users can control this when initializing libprocess.
