Matvey Arye 9c7191e898 Change TIMESTAMP partitioning to be completely tz-independent
Previously, for timezones w/o tz. The range_end and range_start were
defined as UTC, but the constraints on the table were written as as
the local time at the time of chunk creation. This does not work well
if timezones change over the life of the hypertable.

This change removes the dependency on local time for all timestamp
partitioning. Namely, the range_start and range_end remain as UTC
but the constraints are now always written in UTC too. Since old
constraints correctly describe the data currently in the chunks, the
update script to handle this change changes range_start and range_end
instead of the constraints.

Fixes #300.
