Draft: Update google.golang.org/grpc from 1.29.1 to 1.35.1
Update google.golang.org/grpc from 1.29.1 to 1.35.1 (full diff).
Also updates github.com/golang/protobuf from 1.3.3 to 1.4.3 (notable change / full diff).
Also updates gitlab.com/gitlab-org/labkit from 1.0.0 to 1.3.1 to apply labkit!112 (merged) to avoid to use google.golang.org/api
v0.15.0, which still uses the deprecated grpc/naming.
With this MR, we can remove !2975 (merged) since grpc/grpc-go#3990 was resolved in grpc/grpc-go#4021 in google.golang.org/grpc between 1.35.0-dev and 1.35.0.
Possibly replaces !3482 (closed)
