Because the detection of the webroot is not that good, it was removed.
Now, the object id contains the full path of the nextcloud installation.
This changes the installation process a bit, as it will download the
tarball to /tmp rather the webroot.
Also, this commit contains a bit overhaul work.
This type should work, but there are still many things to do here to
work nice and well.
Things that currently not work (well):
- not all parameters work for now
- nextcloud installations in subfolders (e.g. slashes in the object id)
