The requirement of hdsize/4 was not checked anywhere and adding sanity
checks for maxroot<=hdsize/4 would stop users from installing PVE on
smaller disks (see [0]), whereas the installation actually tries its
best to successfully install even on disks below 12GB. So instead of
adding sanity checks, relax the documentation regarding this requirement
and instead refer to the defaults used during installation to provide
guidance for users.

The GUI and TUI installers already implement checks to ensure systems
have the minimum required number of disks available for the various RAID
configurations (min 2 disks for RAID1, min 4 disks for RAID10, etc).
This change adds an early check of the answer file to the
auto-installer, improving the user experience by avoiding failure during
the actual installation.

Instead of having parts of the RAID setup checks scattered in multiple
places, move the core of the checks to implementations of the
ZfsRaidLevel and BtrfsRaidLevel enums. Additionally, also move the unit
tests accordingly.

Adapt the return type of CidrAddressEditView's get_value implementation
for the FormViewGetValue trait to handle errors in case of invalid CIDR
similarly to other (parsing) errors done in the TUIs network dialog.

Add checks for valid subnet mask (greater than /0 and at most /32 for
IPv4). In addition, check if the address entered by the user is valid
within the given subnet, i.e. not a network address or broadcast
address. /31 is considered an exception in accordance with RFC3021 [0],
considering any of the 2 available addresses to be valid host addresses.

Adapt error messages around these checks to follow a similar structure
as in the TUI (<filesystem>: <message>) instead of displaying them as
warnings, since they actually stop users from continuing anyway.
Signed-off-by: Michael Köppl <m.koeppl@proxmox.com>
---
This is mostly to have both the TUI and GUI display actual errors with
context instead of warnings since users cannot continue because it was a
bit irritating to have the TUI display an error with context and the GUI
just saying "Warning". Additionally, the error messages now have a
similar format in both installers. The TUI uses ZFS (RAID0), BTRFS
(RAID0), etc., whereas the GUI uses zfs (RAID0), etc. I decided not to
change that for now since it would be a bit out of scope for this
series, I think. Unifying any informational or error messages
throughout the installers in general would make sense for a future
series, though.
