This PR consists of three parts: * Small refactoring of the fencing APIs in storage_proxy (renames + comments + some functions were extracted) * Implement the fencing for LWT verbs itself. This includes checking the fencing token before and after local replica data accesses. * Two new `test.py` tests in `test_fencing.py`, which check the fencing in some real-world scenarios. Backport: no need -- fencing for LWT requests is needed primarily for LWT over tablets, which is not released yet.

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.
