[ui] Environment with this name already exists -- support for error message from API

[Przemyslaw Kaminski]

1. Open two tabs with Fuel dashboard
2. In first one, create enviroment 'x', finish the wizard
3. In second tab create environment 'x' again
4. Upon clicking finish API returns 409 with plaintext response "Environment with this name already exists"

UI should handle this case displaying an error (currently it moves to first step in wizard). The API response should probably be in JSON format.
