tent/cache config read

Imho, not so good, because I have used the INFO level for `Loading configs for %s under %s`.
So when I do it for `Reading` also, you will see it double, compare:
```
Loading configs for fail2ban under ./config
  Loading files: ['./config/fail2ban.conf']
  Loading files: ['./config/fail2ban.local']
  Loading files: ['./config/fail2ban.conf', './config/fail2ban.local']
Loading configs for jail under ./config
  Loading files: ['./config/jail.conf']
```
```
Loading configs for fail2ban under ./config
Reading configs for fail2ban under ./config
  Loading files: ['./config/fail2ban.conf']
  Loading files: ['./config/fail2ban.local']
  Loading files: ['./config/fail2ban.conf', './config/fail2ban.local']
Loading configs for jail under ./config
Reading configs for jail under ./config
  Loading files: ['./config/jail.conf']
```
