/// @brief Handler that allows to control the behavior of server from tests,
/// and @ref md_en_userver_functional_testing "functional tests with testsuite"
/// in particular.
///
/// It is highly recommended to disable this handle in production via the
/// @ref userver_components "load-enabled: false" option.
///
/// The component must be configured in service config.
///
/// ## Static options:
/// Aside from @ref userver_http_handlers "common handler options" component
/// has the following options:
///
/// Name | Description | Default value
/// ---- | ----------- | -------------
/// testpoint-url | an URL that should be notified in the TESTPOINT_CALLBACK and TESTPOINT_CALLBACK_NONCORO macros | -
/// skip-unregistered-testpoints | do not send testpoints data for paths that were not registered by `testpoint-url` | false
/// testpoint-timeout | timeout to use while working with testpoint-url | 1s
///
/// ## Static configuration example:
///
/// @snippet components/common_server_component_list_test.cpp  Sample tests control component config
///
/// ## Scheme
/// Main user of the scheme is the pytest_userver.client.Client python class.
/// In particular:
/// @code
/// {
///     "action": "run_periodic_task" | "suspend_periodic_tasks" | "write_cache_dumps" | "read_cache_dumps" | "metrics_portability"
///     "testpoints": [<list of testpoints to register>]
///     "reset_metrics": true | false
///     "mock_now": <time in utils::datetime::Stringtime() acceptable format>
///     "invalidate_caches": <...>
