This PR adds an upgrade test for SSTable compression with shared dictionaries, and adds some bits to pylib and test.py to support that. In the series, we: 1. Mount $XDG_CACHE_DIR into dbuild. 2. Add a pylib function which downloads and installs a released ScyllaDB package into a subdirectory of $XDG_CACHE_DIR/scylladb/test.py, and returns the path to bin/scylla. 3. Add new methods and params to the cluster manager, which let the test start nodes with historical Scylla executables, and switch executables during the test. 4. Add a test which uses the above to run an upgrade test between the released package and the current build. 5. Add --run-internet-dependent-tests to test.py which lets the user of test.py skip this test (and potentially other internet-dependent tests in the future). (The patch modifying wait_for_cql_and_get_hosts is a part of the new test — the new test needs it to test how particular nodes in a mixed-version cluster react to some CQL queries.) This is a follow-up to https://github.com/scylladb/scylladb/pull/23025, split into a separate PR because the potential addition of upgrade tests to test.py deserved a separate thread. Needs backport to 2025.2, because that's where the tested feature is introduced.

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.
