This patch adds tests reproducing issue #24581, where Scylla incorrectly parsed "decimal"-type literals in CQL with very high exponents, near or above the 32-bit limit. For example, 1.1234e-2147483647 was incorrectly read as 1.1234E+2147483649, while it should be (as we explain in comments in the test) an error. The tests in this patch failed (in multiple checks) before #24581 was fixed, and pass after it was fixed. These tests all pass on Cassandra 3, confirming our understanding on the limits of "decimal" to be correct. But they fail on Cassandra 4 and 5 due to a regression https://issues.apache.org/jira/browse/CASSANDRA-20723 in Cassandra, that mistakenly limited "decimal" exponents to just 309.

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.
