Incoming message validation

[TimoGlastra]

When a message from another agent is received it is transformed from JSON into a class instance of that message. Most agent message classes already contain decorators from the class-validator package that specify how we want to validate properties. For example the ConnectionInvitationMessage contains decorators to validate.

The Dispatcher class transforms the JSON of a message to a class instance. After the transformation we should use the validate function of the class-validator package to check if the message is valid.

In the future we can send a problem report message from the problem report protocol (#58) if the message is not valid according to the validation (which should be based on the requirements of the RFCs)

• Add validation decorators to all message classes. Also check messages that already contain validation decorators.
• Validate message class instance with class-transormer package after transformation from JSON
• Add appropriate tests
