The API options are required to specify your addons.mozilla.org credentials.
`--api-key`: the API key (JWT issuer) from addons.mozilla.org needed to sign the extension. This is a string that will look something like `user:12345:67`.
`--api-secret`: the API secret (JWT secret) from addons.mozilla.org needed to sign the extension. This is a string that will look something like `634f34bee43611d2f3c0fd8c06220ac780cff681a578092001183ab62c04e009`.
