This patch adds a new expression type, unary_operator, analogous to the existing binary_operator but takes just one operand instead of two. This patch also implements the first and only unary operator type, unary_oper_t::NEG, implementing negation (unary minus) for all numeric types. For fixed-width integer types overflow or underflow results in an error. If the operand is NULL, the result is a NULL as well. The new operator is not yet used by the CQL syntax - our parser doesn't parse arithmetic expressions yet. We also do not plan to use it in the following patch which uses the separate SUB (subtraction) operation, not the new NEG. But since I already implemented a unary minus operator, and we'll surely need it in the future for general arithmentic operations, I thought I might as well include this patch as well.

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.
