…cts (#428)* feat: Make grpc transcode logic work in terms of protobuf python objects(for context: [gRPC Transcoding](https://github.com/googleapis/googleapis/blob/master/google/api/http.proto#L44))Previously it worked on dictionaries only, but that causes problems.In GAPIC the dictionaries are created through the same logic as JSON (there is no better built-in way), thus applying [protobuf json mapping](https://developers.google.com/protocol-buffers/docs/proto3#json) conversion logic in the process. Unfortunately converting a protobuf object to a dictionary and to JSON, although similar, are not the same thing. Specifically the `Timestamp`, `Duration`, `FieldMask`, `uint64`, `int64`, and `*Value` protobuf messages are converted to strings for JSON (instead of being properly converted to dicts for most of those types, and `int64/uint64` converted to `int` respectively). As a result a rountrip that GAPIC was relying on (protobuf object -> dict -> transcode -> protobuf object) did not work properly. For example, when converted to dictionary, every int64 field would be converted to `string` (because it is what proto-JSON mapping spec requires), but later, when we need to rebuild a message from a transcoded dictionary that would fail with the following error:```TypeError: '0' has type str, but expected one of: int```Note, `*Rules` thing from proto-plus does not help, becuase the type may happen inside common native protobuf stub messsages (like `google.type.Money`), fields of which are outside of scope of the proto-plus custom conversion logic.Also, this change greatly simplifies the procedure of transcodding, eliminating multiple conversion steps (to and from dictionaries multiple times) making the whole logic significanly more efficient (python gapics are nutoriously known to be slow due to proto-plus stuff, so efficiency is important) and robust (JSON conversion logic does not interfere anymore with pure protobuf objects grpc transcoding)* reformat code using black* reformat code according to flake8Co-authored-by: Anthonios Partheniou <partheniou@google.com>
