[pve-devel] [RFC kernel-meta] add proxmox-secure-boot-support package

["Fabian Grünbichler" <f.gruenbichler@proxmox.com>]

installing it at least gives the admin a heads up if our base Debian release is
ever faster shipping a newer version of shim or Grub, which would look
(something) like this:

 Reading package lists... Done
 Building dependency tree... Done
 Reading state information... Done
 The following package was automatically installed and is no longer required:
   proxmox-grub
 Use 'sudo apt autoremove' to remove it.
 The following packages will be REMOVED:
   proxmox-secure-boot-support
 The following packages will be upgraded:
   shim-signed shim-signed-common
 2 upgraded, 0 newly installed, 1 to remove and 0 not upgraded.

it also allows us to pull in additional signed packages as they become
available.

it could also be "armed" similar to proxmox-ve, and require some special action
before being removed.. but since the worst case is that the system fails to
boot with SB enabled, which still should be possible to disable on all systems
where PVE normally runs, that might be overkill..
