[Feature Request] Introduce Qualifiers

[jahermosilla]

It would be great to be possible to declare more than one provider bound to the same "bound_type".

Something like:

class UseCase:
    def __init__(self, some_type: SomeType):
        ...

class Dependencies(Group):
    some_type = providers.Factory(
        creator=some_creator,
        bound_type=SomeType,
        #qualifier=None # Default, the "primary"
    )

    another_type = providers.Factory(
        creator=some_another_creator,
        bound_type=SomeType,
        qualifier="another"
    )

class Usage(Group):
    my_use_case = providers.Factory(
        creator=UseCase,
    )

    some_other_use_case = providers.Factory(
        creator=UseCase,
        qualifiers={
            SomeType: "another"
        }
    )

# Resolve directly with container

container.resolve(SomeType, qualifier="another")

@jahermosilla this could work, thanks) I'll think about it.

For now explicit passing providers to kwargs argument can be used in such cases
