Updates vendored Nomad jobspec parser such that parameterized nomad job files can no be parsed and used with Terraform.
Also fixes tests to adhere to new jobspec version, and update documentation to reflect such as well.
Nomad was manually updated, so revert that to the version in master,
remove it from vendor.json and add it to the ignore list.
Update all packages that were in an unknown state to their latest master
commits.
A number of PRs have come through which modified the vendor folder
without recording the proper information. This resets everything back to
the recorded version.
