STATE - Get State Operation should support sending metadata

[perokvist]

The client state operations for "get" does not take a metadata dictionary.
This makes using "partitionKey" in the cosmos state component "impossible".

cosmos state component usage.

Thanks for reporting it @perokvist . I am transferring it to dapr/dapr repo as the grpc GET state api doesn't accept metadata.

ack. I think this should be P1 ?

@yaron2 @amanbha do we want to fix this in this milestone? In this case, we need to add metadata property to all state apis.

@youngbupark this will not be breaking, correct? its addition to existing api and given that today is code freeze, it can come in next release.
