This change was made with the following commands
go mod init
go mod tidy
go mod vendor -v
Revision of github.com/op/go-logging changed because
github.com/anacrolix/torrent requires the current version in its go.mod
# github.com/op/go-logging
yunion.io/x/onecloud/cmd/torrent
github.com/anacrolix/torrent
github.com/elgatito/upnp
github.com/op/go-logging
Content of google.golang.org/grpc changed and it's indeed the case after
checking with the upstream repo. It's very likely that the old content
is wrong.
Some packages like golang.org/x/sys/unix are added because they are
indeeded needed
Some packages are removed as a whole because they are needed anymore
