[Bug 1820768] Re: [SRU] support new cab and new docking firmware upgrade in fwupd 1.2.10

[Bearsh]

Yuan-Chen, I installed fwupd from your ppa. Logitech fw-update works, thanks.
unfortunately system firmware on my xps13 does not as fwupd complains about missing signed bootloader:
"UpdateError:          missing signed bootloader for secure boot: /usr/lib/fwupd/efi/fwupdx64.efi.signed cannot be found"

I hope, once working correctly this ends up either in ubuntu bionic or
at least in 'dell-support' (as 1.2.5-1~somerville1 there can't handle
logitech :()

Bug description:
  * Impact

  Bios vendor is pushing to put the new design into cab file, and also
  new docking DW19 needs the new fwupd to support it.

  That needs new fwupd to support.

  * Background:
   1. most user does firmware update via gnome-software and it talk to fwupd.
   2. only very very limited user will call /usr/bin/fwupdate from the command line.
   3. the new fwupd will need a new fwupd-signed. So we will remove fwupdate-signed.

  * Current test result before we have something in proposed channel:
   1. new fwupd works well with gnome-software, so we should be safe to go.
   2. for those very limited user, they can call /usr/lib/fwupd/fwupdate to replace /usr/bin/fwupdate. so it should be safe to remove fwupdate.

  * Test case

  I
  1. install the new fwupd, and plugin the new docking - DW19.
  2. fwupdmgr get-devices and check if all internal device can properly show
  II.
  1. If you can get new cab file, try to use fwupdmgr install XX.cab to see if can work properly.
  III.
  1. If you can get a machine that have some firmware update pending, try to go gnome-software, and click refresh with the new fwupd, you should be able to see the pending firmware showed there. Which proves that it can properly be integrated with gnome. (ycheng-twn have a laptop with that condition, and he can verify that one)
  IV. As we need to remove fwupdate-signed and install fwupd-sign, we need to test if fwupdate(bionic) work well with fwupd-signed(the new verion in this SRU)

  * Regression potential

  Since the upstream maintainer is back up this upgrade, and he also
  works in a major computer vendor and works closely with the BIOS team,
  it should be fairly low risk.
