[#270] client: Use RPC call instead of Dial

Browse source 
After api-go upgrade created client doesn't establish connection after created,
so RPC call is required to establish and check connection.
RPC call returns status error, so conversion from status error to context error
is required to satisfy Dial contract and unit tests.
