Add option to inject all services implementing a given interface

[maldoinc]

Users should have the option to inject everything that implements some interface or protocol(once they get added).

Could you add some examples of what this issue wants to achieve? That would be super helpful.

There's a few issues of things I imagined would be useful but haven't fully scoped. This being one of them. I always imagined some sort of services: Annotated[List[ServiceInterface], Inject(supports=ServiceInterface]) but it does need some scoping.

The target api is as follows:

def main(
    all_caches: Injected[Set[T]], # This injects a set of all Cache implementations
    all_caches_map: Injected[Mapping[Hashable, T]] # Inject a map<qualifier,
): ...

@abstract
class Cache: ...


@service(qualifier="redis")
class RedisCache(Cache): ...


@service(qualifier="in_memory")
class InMemoryCache(Cache): ...

container = wireup.create_sync_container(service_modules=[importlib.import_module(__name__)])


@wireup.inject_from_container(container)
def main(all_caches: Injected[Set[Cache]], all_caches_map: Injected[Mapping[str, Cache]]):
    for cache in all_caches:
        print(f"Cache: {cache}")

    for name, cache in all_caches_map.items():
        print(f"Cache '{name}': {cache}")


main()

Internally this can be implemented in the registry as a new service for each interface, that creates a function and registers it with itself returning the set/dict containing the impls in _extend_with_services.
