some points after upgrade to 2.3.8

After upgrading to 2.3.8 on Raspbian Stretch I found some points which I think are better to change:

1. /etc/logrotate.d/z-way_server:
   The filesize is increased to very high value. I would prefer to have the previous filesize. Or stay at the old value set by user. It needs so much time to read such a huge logfile.

2. After upgrade, the folders storage and userModules have changed the owner to root. They should have the same owner (pi) and the same user rights as the other folders.

3. config.xml:
   I think it's better to change the default debug level to 1. Or stay at the old value set by user.
