This patch adds a test that takes an sstable with one partition of 13,520
clustering rows (spanning 700 KB in the data file), and attempts to read
various slices CQL rows, counting that we got back the expected number
of rows.
The sstable included here was generated by Cassandra, and includes a
promoted index. Promoted index reading is not supported yet (we will
add it in the next patch), so for now the code will always read the
entire partition from disk; But still the clustering-key filtering is
already functional, and will drop some of the rows as requested,
so this test will pass.
Later, when we add promoted index support, we should check that this test
still passes - promoted index will make the reads in this test more
efficient (which the test cannot verify), but the important thing to check
is that it doesn't break any of these tests.
