:py:class:`Selector` provider selects provider based on the configuration value or other callable.

:py:class:`Selector` provider has a callable called ``selector`` and a dictionary of providers.
The ``selector`` callable is provided as a first positional argument. It can be
:py:class:`Configuration` provider or any other callable. It has to return a string value.
That value is used as a key for selecting the provider from the dictionary of providers.
The providers are provided as keyword arguments. Argument name is used as a key for
selecting the provider.
Full example:
