Add binary storage option

[MikeGoldsmith]

Orleans storage providers should be able store grain state directly in a binary format and not in JSON.

The StorageProvider attribute has a property which indicates if the serialization should be to JSON or not and Orleans has a binary serializer SerializationManager which can serialize data to binary in a none-backward compatible manner. That is one option and there are many others as well.

This would be a really nice feature for storing BLOB data.

Azure provider and many others already support this so by looking at their code one can add the support easily. I'm really short of time these days otherwise I would do it.

Also it can wait until somebody needs it and doesn't have a very high priority

@ashkan-saeedi-mazdeh I'm working on adding an official BinaryTranscoder to the Couchbase SDK, which we can then use as part of this improvement.

[MikeGoldsmith]

There is now a BinaryTranscoder available in the .NET Couchbase SDK from 2.4.6. I'll try to do a PR to switch over what Transcoder to use over the next couple of days.

Awesome, Keep in mind that JSON should remain an option due to it being queryable and more friendly to versioning, The StorageProvider attribute passed to the provider has a property IsJson or something like that. I'm very busy for the next month but will review the PRs for sure at minimum.

Yeah, plan is to make it configurable. Default would be JSON.
