Just Click Shop

Mock for the Braspag Protected Credit Card service.

Three requests need to be covered in order to fulffil the whole flow, including the `SOAP` handshake:

1. The client requests the WSDL definition of the service.
2. Then the credit card info can be saved (`CreditCardSave`)
3. Finally the payment is authorized through the received `JustClick` key (`JustClickShop`)

There are still some details to update:

* [ ] Check the logs to find out what is the format of some fields
* [ ] Ensure all fields are being parsed and returned according with the real API, regardless of documentation inconsistencies
* [ ] Handle (or not) invalid/malformed requests
In `baby-braspag` gem we have this:

```ruby
PROTECTED_CARD_PRODUCTION_URL = "https://cartaoprotegido.braspag.com.br/Services"
PROTECTED_CARD_HOMOLOGATION_URL = "https://homologacao.braspag.com.br/services/testenvironment"
```

https://github.com/Baby-com-br/braspag/blob/master/lib/baby-braspag/connection.rb#L8-L9

Shouldn't the path be `/services/testenvironment` then?
