Vendor out of sync

[fntlnz]

The Gopkg.lock and Gopkg.toml are out of sync.

dep status
Lock inputs-digest mismatch. This happens when Gopkg.toml is modified.
Run `dep ensure` to regenerate the inputs-digest.

Also seems that there's a manifest.json which has another whole set of dependencies and should be deleted since it's used by nothing

I don't remember something like this. I usually don't modify these files. Are you confident enough to open a pr? In other hands I will try to fix it as soon I will have a laptop
