These two streams mostly play together. The former provides an input_stream from read from in-memory temporary buffers, the latter wraps it to limit the size of provided temporary buffers. Both are used to test contiguous data consumer, also the buffer_input_stream has a caller in sstables reversing reader. This PR removes the buffer_input_stream in favor of seastar memory_data_source, and moves the limiting_input_stream into test/lib. Enanching testing code, not backporting Closes scylladb/scylladb#28352 * github.com:scylladb/scylladb: code: Move limiting data source to test/lib util: Simplify limiting_data_source API util: Remove buffer_input_stream test: Use seastar::util::temporary_buffer_data_source in data consumer test sstables: Use seastar::util::as_input_stream() in mx reader

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.
