  Create a client to access Pairing API.

  `pairing_url` is the base URL of the Astarte Pairing API instance the client will connect to, e.g. `https://astarte.api.example.com/pairing` or `http://localhost:4003` for a local installation.

  `realm` is the realm that the API will access

  `opts` is a keyword list of additional options detailed below

  ## Options
    * `:auth_token` - Auth token that will be used as authorization when accessing Pairing API. This can be a JWT to use it with `Astarte.API.Pairing.Agent` or a credentials secret to use it with `Astarte.API.Pairing.Device`.
