In this patch we add to our expressions oper_t::SUB, for subtraction, analogous to the ADD from the previous patch. The only reason why we need a separate SUB operation and can't just combine ADD with a unary minus (NEG) operator is the minimum integer in fixed-sized integer. For example, 8-bit integers have the range -128...127. A subtraction like -1 - (-128) is valid (its value is 127) but the negation of (-128) would be invalid (128). One of the tests we add in this patch validates this fact. Signed-off-by: Nadav Har'El <nyh@scylladb.com>

If you can use an existing folder, consider adding your test to it. New folders should be used for new large categories/subsystems, or when the test environment is significantly different from some existing suite, e.g. you plan to start scylladb with different configuration, and you intend to add many tests and would like them to reuse an existing Scylla cluster (clusters can be reused for tests within the same folder).
To add a new folder, create a new directory, and then
copy & edit its suite.ini.
