Adds the test_hints_consistency_during_decommission test which reproduces the failure observed in scylladb/scylla-dtest#4582. It uses error injections, including the newly added topology_coordinator_pause_after_streaming injection, to reliably orchestrate the scenario observed there. In a nutshell, the test makes sure to replay hints after streaming during decommission has finished, but before the cluster switches to reading from new replicas. Without the fix, hints would be replayed to the decommissioned node and then would be lost forever after the cluster start reading from new replicas.
Scylla in-source tests.

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.
