Continuing the read once it is aborted (e.g. due to timeout) is a waste of resources, as the produced results will be discarded. Poll the permit's abort exception in the memtable and cache reader's fill_buffer(). This results in one poll per buffer filled (8KB of data). We already have similar poll for sstable readers, as disk reads are usually much heavier and therefore it is more important to stop them ASAP after abort. Cache and memtable reads are usually quick but not always, hence it is important to also have polling in the cache and memtable readers. Refs: #11469 Fixes: #28148 Closes scylladb/scylladb#28149

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.
