#set_provider(provider, domain: nil) ⇒ Object

When switching providers, there are a few lifecycle methods that need to be taken care of.

1. If a provider is already set, we need to call `shutdown` on it.
2. On the new provider, call `init`.
3. Finally, set the internal provider to the new provider
