prometheus: add histogram support to exporter (#601) 
This PR adds histogram support to the prometheus exporter.

- Adds a new aggregator selector that returns a histogram for `MeasureKind`.
  The selector can be constructed using `simple.NewWithHistogramMeasure`
- Adds support for histogram aggregators in prometheus collect method.

With this PR, the default selector is changed to use histograms.

In order to support the prometheus histogram, the `aggregator.Histogram`
interface is extended with the `Sum` method.

fixes #487
