This patch adds a reproducing test for issue #11588, which is still open so the test is expected to fail on Scylla ("xfail), and passes on Cassandra. The test shows that Scylla allows an out-of-range value to be written to timestamp column, but then it can't be read back. Signed-off-by: Nadav Har'El <nyh@scylladb.com> Closes #11864
