Ernest Zaslavsky 834eed10d9 test: fix use-after-free in start_docker_service retry path
start_docker_service is a coroutine that took docker_args and
image_args by const reference. Its caller start_fake_gcs_server
is a regular function that passes temporaries (initializer lists)
and immediately returns a future. The temporaries are destroyed
when the caller returns, leaving the coroutine holding dangling
references.

On the first loop iteration this works by luck (memory not yet
reused), but on retry (after "address already in use") the
params.append_range(image_args) reads freed memory, causing
use-after-free that manifests as std::bad_alloc or broken_promise
in non-sanitizer builds.

Fix by taking docker_args and image_args by value so the coroutine
frame owns the vectors for its entire lifetime.

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.
