add support for azure-devops (#160)

- azure-cli defaults to placing its azure-devops cache into
  '$HOME/.azure-devops' unless the environment variable
  'AZURE_DEVOPS_CACHE_DIR' is set.
- azure-devops.json checks for the '~/.azure-devops' directory and
  suggests exporting `AZURE_DEVOPS_CACHE_DIR` as
  '"$XDG_CACHE_HOME"/azure-devops'.
