Capability to change envoy histogram buckets

[themkarimi]

Is it possible to change envoy histogram buckets in contour? we have done this before in envoy using this configuration:

      histogram_bucket_settings:
        - match:
            safe_regex:
              google_re2: {}
              regex: ".*" 
          buckets:
            - 1
            - 10
            - 50
            - 250
            - 500
            - 1000
            - 5000
