Vendoring of generated nomad API does not work

[ThomasObenaus]

In the current configuration a dep ensure will lead to build errors due to incompatibility between the generated nomad API code and the code-generator used for this.

Due to that the vendoring folder had to be checked in.

Just found out that nomad builds with this revision of github.com/ugorji/go.

Thus I pinned it to this one in the toml file:

# Fixed to revision c88ee250d0221a57af388746f5cf03768c21d6e2 because of build issues inside github.com/hashicorp/nomad
[[override]]
  name = "github.com/ugorji/go"
  revision = "c88ee250d0221a57af388746f5cf03768c21d6e2"
