• Support per-org api tokens in keychain and keyring:

  # Keychain, on macOS
  security add-generic-password -s api.buildkite.com/v2/organizations/YOUR-ORGANIZATION -a YOUR-USERNAME -w
  
  # still falls back to global token
  security add-generic-password -s api.buildkite.com -a YOUR-USERNAME -w
  

  # Keyring, for Linux and friends
  # pip install keyring
  keyring set "api.buildkite.com/v2/organizations/${BUILDKITE_ORGANIZATION}" "$USER"
  
  # still falls back to global token
  keyring set api.buildkite.com "$USER"
  

• Send git-buildkite/v0.6.0 as a user agent when triggering builds
