add serviceclient exceptions (#989)

What changed?

added all exceptions to match thrift exceptions
added ErrorMapper which maps StatusRuntimeException to ServiceClientException
Why?

thrift exceptions are used across Java SDK. It's easier to abstract the protocol level error handling by introducing internal exception layer
