Add hydraclick CLI configuration

[Guillemdb]

We would like to use hydraclick to manage the template configurations.

This will allow us to store .yaml files that will allow us to compose configurations using hydra. Once we have a dictionary containing the configuration, we will transform it into a cookiecutter.json file.

In order to close this issue we need to:

• Create a config folder containing the default configutarion file.
• Add hydraclick so we can load the configuration.
• Transform a yaml config dict into JSON.
