ctx_zap is a ctxlogger that is backed by Zap
It accepts a user-configured zap.Logger that will be used for logging. The same zap.Logger will
be populated into the context.Context passed into gRPC handler code.
You can use ctx_zap.Extract to log into a request-scoped zap.Logger instance in your handler code.
As ctx_zap.Extract will iterate all tags on from grpc_ctxtags it is therefore expensive so it is advised that you
extract once at the start of the function from the context and reuse it for the remainder of the function (see examples).
Please see examples and tests for examples of use.

func AddFields(ctx context.Context, fields ...zapcore.Field)AddFields adds zap fields to the logger.
func Extract(ctx context.Context) *zap.LoggerExtract takes the call-scoped Logger from grpc_zap middleware.
It always returns a Logger that has all the grpc_ctxtags updated.
func TagsToFields(ctx context.Context) []zapcore.FieldTagsToFields transforms the Tags on the supplied context into zap fields.
func ToContext(ctx context.Context, logger *zap.Logger) context.ContextToContext adds the zap.Logger to the context for extraction later. Returning the new context that has been created.
