Currently in services, the `contract` step is only used to define where the contract will be called in the execution flow. Then, a `Contract` class has to be defined with validations in it. This patch allows the `contract` step to take a block containing validations, attributes, etc. directly. No need to then open a `Contract` class later in the service. It also has a nice side effect, as it’s now easy to define multiples contracts inside the same service. Before, we had the `class_name:` option, but it wasn’t really useful as you had to redefine a complete new contract class. Now, when using a name for the contract other than `default`, a new contract will be created automatically using the provided name. Example: ```ruby contract(:user) do attribute :user_id, :integer validates :user_id, presence: true end ``` This will create a `UserContract` class and use it, also putting the resulting contract in `context[:user_contract]`.
