receiver/statsd

Is your feature request related to a problem? Please describe.

When sending summary, I would like to choose the percentiles instead of getting default hardcoded percentiles - 0, 10, 50, 90, 95, 100. See https://github.com/coralogix/opentelemetry-collector-contrib/blob/main/receiver/statsdreceiver/protocol/metric_translator.go#L17

Describe the solution you'd like

receivers:
  statsd:
    endpoint: "0.0.0.0:8125"
    enable_metric_type: true
    is_monotonic_counter: false
    aggregation_interval: 10s
    timer_histogram_mapping:
      - statsd_type: "timing"
        observer_type: "summary"
        summary: 
          percentiles: [0, 10, 50, 90, 95, 99, 100]
