if webhosting is present we should manage manage the apache user
in the user group after it have been created.

We are now able to select how apache should log accesses. These
modes are:

* default: as you would use it
* semianonym: no ips are logged for CustomLog, ErrorLog still logs
              ips
* anonym: no ips are logged for CustomLog, ErrorLog is sent to
          /dev/null
* nologs: all logs are sent to /dev/null

run_gid_name should per default be the same as the group for the
sftponly user. However, as can now set that one, we should be detect
if a groupname is set and use that one for the run_gid_name and not
as by default the $name.
