test_compaction_with_multiple_regions() has two calls to std::shuffle(),
one using std::default_random_engine() has the PRNG, but the other, later
on, using the std::random_device directly. This can cause failures due to
entropy pool exhaustion.
Fix by making the `random` variable refer to the PRNG, not the random_device,
and adjust the first std::shuffle() call. This hides the random_device so
it can't be used more than once.

We use boost test logging primarily to generate nice XML xunit
files used in Jenkins. These XML files can be bloated
with messages from BOOST_TEST_MESSAGE(), hundreds of megabytes
of build archives, on every build.
Let's use seastar logger for test logging instead, reserving
the use of boost log facilities for boost test markup information.
1. Move tests to test (using singular seems to be a convention
in the rest of the code base)
2. Move boost tests to test/boost, other
(non-boost) unit tests to test/unit, tests which are
expected to be run manually to test/manual.
Update configure.py and test.py with new paths to tests.
