Before returning, the partition should be unmounted, as it is not needed
anymore after this point.
This also prevents some funny error that occurs if the installation
fails due to some error. The next time `proxmox-fetch-answer` is run, it
cannot mount the answer partition anymore, due to being already mounted.
For now sure. If we add additional plugins to fetch the answer file via a URL,
we might want to place the ssl fingerprint on the same partition. Then we would
have to either mount it again, or wait with the unmount until we have reached
the end of going through the plugins, as a cleanup measure.
Actually, I think we want to keep it mounted. A warning when running the
`proxmox-fetch-answer` once more, should be okay and will mainly happen during
testing but not in a real-life scenario. It also makes it easy to place
additional data on the partition and use it in a pre- or post-command. For
example, scripts, config files, deb packages and so forth.
