[Bug] Access mainick_keycloak_client.yaml before even created when installing the library

Possible solution
When installing the library the first time, check if the yaml is properly created (check if the file yaml exist and the required fields exists). If not than create a default

appuser@cc8aad1fbc04:/var/www/symfony$ composer require mainick/keycloak-client-bundle

According to the instructions in the "Configuration" chapter of the README on GitHub, you must create the mainick_keycloak_client.yaml file before proceeding with the installation. There is an open issue #1 to automate the file creation using Symfony Flex.
