This patch reduces the permissions on the install directory to just the root user and also fixes the ansible-lint issue by specifying the `mode`.
For all container mounted volumes, the ansible-lint rule is disabled, as the container takes care of the permissions etc.
This patch renames all roles with a `-` to `_`, to comply with the ansible-lint rule 106. As collection roles are now also limited to these symbols and this will make it easier to move them later.
