Planned deprecation - SDK REST client

We are planning to deprecate the experimental REST client in the Exabel Python SDK. You will not be affected by this change, unless you use the SDK and have explicitly chosen to use the REST client in your data pipelines.

Exabel Python SDK - REST client

Planned deprecation date: SDK 3.7.0 release / June 2022 (REST client still available, but with warnings)
Planned removal date: SDK 4.0.0 release / 3Q or 4Q 2022 (REST client will no longer be available in SDK)

We are deprecating the experimental REST client that was enabled by the use_json flag of the Python SDK. New operations will not support the use_json flag, and use_json will no longer be supported in from version 4.0 of the Exabel Python SDK. use_json forces the client to connect using JSON/HTTPS towards the Exabel servers instead of gRPC. Going forward, the Python SDK will only use gRPC, which is a much more efficient protocol.
