Patryk Jędrzejczak a41d7a9240 Merge 'test_lwt_shutdown: fix flakiness by removing storage_proxy::stop injection' from Petr Gusev
The storage_proxy::stop() is not called by main (it is commented out due to #293), so the corresponding message injection is never hit. When the test releases paxos_state_learn_after_mutate, shutdown may already be in progress or even completed by the time we try to trigger the storage_proxy::stop injection, which makes the test flaky.

Fix this by completely removing the storage_proxy::stop injection. The injection is not required for test correctness. Shutdown must wait for the background LWT learn to finish, which is released via the paxos_state_learn_after_mutate injection. The shutdown process blocks on in-flight HTTP requests through seastar::httpd::http_server::stop and its _task_gate, so the HTTP request that releases paxos_state_learn_after_mutate is guaranteed to complete before the node is shut down.

Fixes scylladb/scylladb#28260

backport: 2025.4, the `test_lwt_shutdown` test was introduced in this version

Closes scylladb/scylladb#28315

Scylla in-source tests.

For details on how to run the tests, see docs/dev/testing.md

Shared C++ utils, libraries are in lib/, for Python - pylib/

alternator - Python tests which connect to a single server and use the DynamoDB API unit, boost, raft - unit tests in C++ cqlpy - Python tests which connect to a single server and use CQL topology* - tests that set up clusters and add/remove nodes cql - approval tests that use CQL and pre-recorded output rest_api - tests for Scylla REST API Port 9000 scylla-gdb - tests for scylla-gdb.py helper script nodetool - tests for C++ implementation of nodetool

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.
