The new patch serialize the duration as an unsigned long and accept {{us}} and
{{µs}} as microsecond symbol. The patch also add some testing for JSON. Adding
tests for MV was not possible due to the fact that the Java driver does not
recognize yet the {{Duration}} type.

> For CASSANDRA-11871 or to allow queries with {{WHERE}} clause like:
> {{... WHERE reading_time < now() - 2h}}, we need to support some duration
> type.
> In my opinion, it should be represented internally as a number of
> microseconds.
