This PR

This adds support for mapping a client name onto a given provider, while still providing backwards compatibility to existing clients.

Related Issues

Refs open-feature/ofep#56
Fixes: #442

Follow-up Tasks

I still need to clean up documentation around this to note the difference between a "default provider" and a client-specific provider.

How to test

Not sure about testing, but I'd especially love eyes on the thread safety. I don't think ConcurrentHashMap is doing a lot of work here, given we have to use locks to support getProviderForClientOrDefault. If you have a better way, I'm all ears.

I still need to clean up documentation around this to note the difference between a "default provider" and a client-specific provider.

If you think it's worth it, it could be something we mention in the glossary.

There's no such thing as "API without a provider set" anymore. We now default to NoOpProvider in the API (not client).

👍 for the noop default provider. This ensures null safety where possible.

Nope (but lets' not release until all this is done, IMO).
