Switch mapping/aggregations over to java time ()
This commit moves the aggregation and mapping code from joda time to
java time. This includes field mappers, root object mappers, aggregations with date
histograms, query builders and a lot of changes within tests.

The cut-over to java time is a requirement so that we can support nanoseconds
properly in a future field mapper.
