Distributed tests for {@link Statistics}.

<p>
VM0 performs puts and VM1 receives updates. Both use custom statistics for start/end with
increment to add up puts and updates. Then validation tests values in stat resource instances and
uses StatArchiveReader. Both are tested against static counters in both VMs.

<p>
This test mimics hydratest/locators/cacheDS.conf in an attempt to reproduce bug #45478. So far
this test passes consistently.
