Configurable file/directory mode

[limitusus]

🗣️ Foreword

I would like the logged-in users to be able to read nginx config files and logs.

:person_frowning: Problem Statement

This cookbook always creates log directories with 0750 and config files with 0640, so non-administrative users cannot read them.

❔ Possible Solution

File/directory mode 0750 and 0640 be the default, but I would be happy if they're configurable.

⤴️ Describe alternatives you've considered

edit_resource method can override modes, but it does not seem the best.

➕ Additional context

Shouldn't be too difficult, I'll take a look into it.
