[MISC] Catch and warn on malformed configuration yaml (#1089)
If the configuration yaml is poorly indented or special values are not appropriately escaped Authelia attempts to load said configuration and fails.

This attempts to unmarshal the config into an empty interface to catch and warn on malformed yaml.

Using the example from issue https://github.com/authelia/authelia/issues/1053#issuecomment-634791662

```yaml
host: 0.0.0.0
port: 9091
log_level: debug

  period: 30

  domain: example.com

  max_retries: 3
  find_time: 120
  ban_time: 300

storage:
  mysql:
    host: example.com
    port: 3306
    database: authelia
    username: authelia
    password: example.com

notifier:
  smtp:
    username: example.com
    password: example.com
    host: smtp.gmail.com
    port: 465
    sender: example.com
```

We would actually get a more meaningful error which helps pinpoint the issue:
`Error malformed yaml: line 23: did not find expected alphabetic or numeric character`
