  @moduledoc """
  Locate a ID of a resource.  This can be done by name or tag.

       doex id <--resource_type> <resource_name>

  Or, by tag

      doex droplets.id <--resource_type> <tag> --tag

  If by tag, it will grab the `latest`.

  The supported resources include

        --droplets       # Locate a droplet's ID
        --snapshots      # Locate a private image's ID (aka snapshot ID)
        --floating-ips   # Locate a floating ip ID (aka snapshot ID)

  For example

      doex id my_app --droplets

  Droplets are also the default, so the `--droplets` can be omitted.

      doex id my_app

  If you have a specific config file, `mix help doex.config` then add it as an environment variable

      DOEX_CONFIG=/tmp/my.doex doex id my_app
