Acquire a configuration class from the provider. The requested class will be a simple Java object that when returned, and can be
interacted with using getters and other standard mechanisms. Configuration classes may themselves contain other configuration
objects, which will be recursively acquired if marked @Configuration. Any fields marked @Encrypted will be decrypted, any fields
marked and any validation annotations will be processed.

@param configClass the class that represents your configuration
@param <T> the class that represents your configuration
@return the configuration class requested, if it can be deserialised
@throws ConfigurationException if the configuration class cannot be acquired or deserialised
