Please add support for aws_extended_statistics as done in https://github.com/prometheus/cloudwatch_exporter/pull/57

We're trying to get the TargetResponseTime metrics as described in the docs and as noted:

Statistics: The most useful statistics are Average and pNN.NN (percentiles).

So I tried:

      - aws_namespace: 'AWS/ApplicationELB'
        aws_metric_name: 'TargetResponseTime'
        aws_statistics: ['p90', 'p95', 'p99']
        aws_dimensions: ['TargetGroup', 'LoadBalancer']
        aws_dimensions_select_regex:
          TargetGroup: .*
          LoadBalancer: app/production-.*

and just aws_statistics: ['p95']:

      - aws_namespace: 'AWS/ApplicationELB'
        aws_metric_name: 'TargetResponseTime'
        aws_statistics: ['p95']
        aws_dimensions: ['TargetGroup', 'LoadBalancer']
        aws_dimensions_select_regex:
          TargetGroup: .*
          LoadBalancer: app/production-.*

But both returns this error in the logs:
