Spruce Release v1.0.2

New Features

• spruce json is a new subcommand. It allows you to pipe yaml through spruce
  and get json-compatible output.

Bug Fixes

• Fixed the (( vault )) operator to honor tokens generated from vault auth
• Fixed the (( vault )) operator to handle HTTP redirects from the Vault API

Miscellaneous

We've updated the CI pipeline to be more awesome. It now generates + uploads
binaries directly to the release as artifacts, without the silly gzip + version
number embedding that used to occur. If you have anything that is automatically
downloading spruce from the latest release, it is likely that you will need to
update your workflow. (THIS IS A BREAKING CHANGE)
