Define py27 assertFoo methods for py26

Frequent issue a test case is failing with py26,
because the used assert method like the assertGreaterEqual
is not defined.

Adding unittest2.TestCase to the base testclass when running
tempest with py26.

add dstat to our list of statistics collectors

this will probably become the replacement for sysstat and pidstat
in the gate, but for now, just add it to the list, so we can start
getting data with it and make sure it's useful enough to drop the
others.
