Implement flagd provider

[toddbaert]

We need to build a gRPC flagd provider. This entails:

• Pulling the proto definitions as a submodule
• building the c# bindings, likely using https://github.com/grpc/grpc-dotnet
• implementing the provider interface using the bindings above
• adding tests
• adding doc

See: https://github.com/open-feature/java-sdk-contrib/tree/main/providers/flagd

@toddbaert do you mind if I pick this one up?

[toddbaert]

Not at all!

The JS impl may also interest you. Feel free to ask myself or @james-milligan for help if you run into issues or anything is unclear

@toddbaert sorry been pretty busy with work lately. I've done a basic implementation of flagd, still need to write tests, and add XML docs. You're welcome to contribute otherwise ill keep plugging away in my spare time.

Hey, there is a flagd provider in nuget on version 0.1.0 which links back to this repository. Would it be the branch for this issue?

It looks as thought the build is failing due to linting rules ?

Are there any missing commits, otherwise I may be able to find some time to plod away at it.

Hey @jonoabroad, the flagd provider in nuget is basically a stub. It was intended to test the deployment process of the monorepo. @benjiro started the initial implementation in this PR but you're welcome to contribute.

Thanks to @bacherfl, we now have a flagd provider. I'm going to close this we have the following tickets to advance the implementation further.

@jonoabroad The flagd implementation is complete, FYI: https://github.com/open-feature/dotnet-sdk-contrib/tree/main/src/OpenFeature.Contrib.Providers.Flagd
