This brings in a bugfix for analyzing variables inside relative traversal
expressions in HCL, and a cosmetic bugfix in cty for GoString of
cty.NullVal(cty.DynamicPseudoType).
This also updates some other packages, as a result of running "go get -u".
This includes a bugfix to the cty/msgpack package to ensure correct
decoding of unknown and null values.
This also includes updates to cty's dependencies.
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.
The original contents of `vendor` were inadvertently captured with an
older version of `godep`. Here, we recapture dependencies by running the
following:
```
godep restore -v
cat Godeps/Godeps.json | jq -r '.Deps[].ImportPath' | xargs godep update -v
```
The newer godep makes the following changes as it captures dependencies:
* Skips test files
* Copies `LICENSE` / `PATENTS` files
There is also an additional diff in `golang.org/x/sys/unix` that looks
very similar to the diff between `master..c65f27f` in that repo, so I'm
guessing that dependency was accidentally captured from master instead
of the commit saved to `Godeps.json`.
All in all, these changes should all be "more correct" and result in
smaller diffs for any future updates made to dependencies.
