ServiceProviderImplementationWrapper

This class provides a art service to wrap a LArSoft service provider interface.

The behaviour of the implementations is not constrained by this interface. It only adds support for lar::providerFrom() function.

Implementations must override do_provider() to return a pointer which provider() will forward to the caller.
