The goal is to remove almost all references to the golang.org/x/net/context package. github.com/gogo/protobuf => v1.2.1 google.golang.org/grpc => v1.19.1 github.com/grpc-ecosystem/grpc-gateway => v1.18.5 It also replaces github.com/cockroachdb/cmux by github.com/soheilhy/cmux because of [1] which fixes #3909 incidentally.
