When performing an image upgrade and Linux Kernel command-line option that
should be passed via GRUB to the Linux Kernel are missing on the first boot.
This is because when generating the GRUB command-line via the op-mode scripts
the CLI nodes defining the options are not honored.
This commit re-implements the code-path in op-mode which generates the strings
passed via GRUB to the Linux Kernel command-line.
NOTE: If (for a yet unknown reason) a Kernel command-line option string changes
during a major - or minor - upgrade of the Linux Kernel, we will need to adapt
that logic and possibly call a helper from within the NEW updated image rootfs.
Thus we can ship future information back into the past like the "Grays Sports
Almanac" from Back to the Future Part II.

To parse variables with `=` a variable name should be limited by alphanumerical

Add system image in compatibility mode would set the default boot
without reference to console_type; fix the translation of default to
the correct index in compat grub.cfg.

To iterate files on ext* file systems GRUB reads their inodes one by one,
ignoring names. This breaks our configuration logic that relies on proper
loading order.
This commit adds a helper `sort_inodes()` that needs to be used whenever GRUB
configuration files are created. It recreates files, changing their inodes in a
way where inodes order matches alphabetical order.

Add util function to set serial console speed in accordance with revised
GRUB file structure; in keeping with the intentions of the config_mode
script, adjust the GRUB var 'console_speed' to only modify ttyS0.

This fix moves from partprobe to partx to rescan the partition table on an affected disk.

T5828: fix grub installation on arm64-efi machines
|
|
|
|
Since the migration of GRUB handling to vyos-1x, the grub install
sequence has hardcoded references to x86.
Change the GRUB sequence so it can work on arm64 as well.

This commit allows management of system images with either new or legacy
tools: 'add/delete/rename system image' and 'set default' are translated
appropriately on booting between images with the old and new tools.
Consequently, the warning of the initial commit of T4516 is dropped.

This commit adds the whole set of system image tools written from the scratch in
Python that allows performing all the operations on images:
* check information
* perform installation and deletion
* versions management
Also, it contains a new service that will update the GRUB menu and keep tracking
its version in the future.
WARNING: The commit contains non-reversible changes. Because of boot menu
changes, it will not be possible to manage images from older VyOS versions after
an update.
