Changes
-------
Adding bug field so this shows up on JIRA
Summary
-------
HBASE-2578 - Add ability for tests to override server-side timestamp setting
(currentTimeMillis).
The solution in this patch ensures that tests use a different timestamp with a
minimal change to the production code paths.
One question I would like to know is whether the change that was made to
HRegion.FIXED_OVERHEAD would cause any other side effects.
This addresses bug HBASE-2578.

>
> Many of our tests use client APIs which do not set explicit stamps. This
> creates weird timing issues with tests running on different systems because
> sometimes a set of operations happens in the same millisecond and other times
> they do not.
> We should have a way for a test to specify it's own way of generating the
> timestamps (for example, could always increment by 1 ensuring forward
> progression in time).
