Creating catalog provider bundles

``di.DeclarativeCatalog.Bundle`` is a limited collection of catalog providers.
While catalog could be used as a centralized place for particular providers
group, such bundles of catalog providers can be used for creating several
limited scopes that could be passed to different subsystems.

``di.DeclarativeCatalog.Bundle`` has exactly the same API as

Each ``di.AbstractCatalog`` has a reference to its bundle class -

Each ``di.DeclarativeCatalog`` has a reference to its bundle class -
``di.DeclarativeCatalog.Bundle``. For example, if some concrete catalog has name
``SomeCatalog``, then its bundle class could be reached as
``SomeCatalog.Bundle``.
``di.AbstractCatalog.Bundle`` expects to get the list of its catalog providers
``di.DeclarativeCatalog.Bundle`` expects to get the list of its catalog providers
as positional arguments and will limit the scope of created bundle to this
list.
