MAR-162: Make the default_https_tls_certificate and default_https_tls_key parameters mandatory:

- Dropped the defaults from web_server role.
- Updated group variables in role tests.
- Changed the key/certificate file extensions to be more descriptive.
- Updated role reference documentation.
- Updated usage instructions to include the mandatory parameters.
