Botond Dénes b18d9e5d0d Merge '[Backport 6.0] make enable_compacting_data_for_streaming_and_repair truly live-update' from ScyllaDB ...

This config item is propagated to the table object via table::config. Although the field in `table::config`, used to propagate the value, was `utils::updateable_value<T>`, it was assigned a constant and so the live-update chain was broken.
This series fixes this and adds a test which fails before the patch and passes after. The test needed new test infrastructure, around the failure injection api, namely the ability to exfiltrate the value of internal variable. This infrastructure is also added in this series.

Fixes: https://github.com/scylladb/scylladb/issues/18674

- [x] This patch has to be backported because it fixes broken functionality
