Releasing

In order to create a new release, follow these steps

1. Create local tag and binaries

./scripts/build-all.sh release VERSION_NUMBER #(e.g. 0.7.0)

1. Copy the output of the previous command from the first line (should be '- name: Firehose Plugin' to the last checksum line (should be something like checksum: fde5fd52c40ea4c34330426c09c143a76a77a8db)
2. Push the tag git push --follow-tags
3. On github, create new release based on new tag here
4. Upload the three binaries from the ./bin folders to the release (Linux, OSX and Win64)
5. Fork this repo and clone it locally
6. Edit the repo-index.yml to override the existing section about the firehose plugin with the text previously copied in Step 2.
7. Run go run sort/main.go repo-index.yml in the cli-plugin-repo to alphabetize the properties
8. Run BINARY_VALIDATION=true go test
9. Push the change to your fork
10. Create a PR against the original repo
