ThreadStats: metric type change

ThreadStats count metrics (produced from the increment/decrement and histogram methods) are now reported with the count/rate metric type, instead of gauge.
As a result, for the corresponding metrics:

1. Metric queries can use the .as_count()/ .as_rate() functions to switch between count and rate representations.
2. The default time aggregation uses a sum instead of an average. This may affect the representation of existing metric queries, thus, monitors' definitions and metric graphs.

See #242 (thanks @nilabhsagar) for more details.
