Add `make_data_or_index_source` to the storages to utilize new S3 based data source which should improve restore performance * Introduce the `encrypted_data_source` class that wraps an existing data source to read and decrypt data on the fly using block encryption. Also add unit tests to verify correct decryption behavior. * Add `make_data_or_index_source` to the `storage` interface, implement it for `filesystem_storage` storage which just creates `data_source` from a file and for the `s3_storage` create a (maybe) decrypting source from s3 make_download_source. This change should solve performance improvement for reading large objects from S3 and should not affect anything for the `filesystem_storage` No backport needed since it enhances functionality which has not been released yet fixes: https://github.com/scylladb/scylladb/issues/22458 Closes scylladb/scylladb#23695 * github.com:scylladb/scylladb: sstables: Start using `make_data_or_index_source` in `sstable` sstables: refactor readers and sources to use coroutines sstables: coroutinize futurized readers sstables: add `make_data_or_index_source` to the `storage` encryption: refactor key retrieval encryption: add `encrypted_data_source` class

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.
