52c1c4c5ab [#290] client: Add WithURIAddress option
Add `WithURIAddress` option to client.
It parses passed address with
`url.ParseRequestURI` function and
use(or not) TLS over grpc connection
based on retrieved scheme('grpc' or
'grpcs').

22ce8e13cc [#196] rpc/client: Implement Client.Conn method
Implement `Client.Conn` which returns the connection of the underlying
transport client. The method is going to be used for forwarding the
connection to superior clients.

30c6ca0714 [#263] Implement client for exchanging raw Protobuf messages
Implement generic `Client` that can communicate with the remote server via
protobuf `Message`'s. The client can uniformly execute any protobuf RPC
on the remote server using any of the supported transport protocols.
Currently only gRPC protocol is supported.

Additionally implement helpful functions to transmit messages by one of the
flow types: unary, client- or server-side stream.

c61656a43f [#263] Define generic protobuf message
Define `Message` interface of the generic protobuf message. In the initial
implementation, the message should be convertible to and from related gRPC
message.

Implement encoding functions over the `Message` that can:

 * unmarshal the `Message` via related gRPC message;
 * decode the `Message` from JSON format via related gRPC message;
 * encode the `Message` to JSON.

Implement nested `test` package for testing the implementation.

cf765a61a6 [#263] Implement client for exchanging raw messages using gRPC protocol
Implement gRPC client that can uniformly execute any RPC on the remote
server. In the primary implementation, the client is a thin wrapper over
gRPC client connection that is required to create the client. In the future,
it is planned to expand the library with convenient functionality.
