Bug description:
  [Impact]
  Crash dump support doesn't work by default on any known arm64 platform. Users have to figure out working incantations for the crashkernel= parameter and the parameters passed to the crash-dump kernel themselves and manual edit 2 different config files.

  [Test Case]
  Using either a Centriq 2400 or a Cavium ThunderX CRB (these platforms are known to support crashdump), and with a kernel >= 4.13 (xenial-ga did not support crashdump):

  sudo apt install kdump-tools
  (reboot, so crashkernel= is added to the kernel commandline)
  echo c | sudo tee /proc/sysrq-trigger

  Crash dump should occur, with artifacts collected in /var/crash.

  If you want to verify that the dump is usable, install the
  corresponding linux-image-<ver>-dbgsym package and run:

  sudo crash /usr/lib/debug/boot/vmlinux-<ver>
  /var/crash/<crash>/dump.<crash>

  crash should successfully load, placing you at a "crash>" prompt. At that prompt, you can issue the 'bt' command to see a backtrace.
  Note: you need crash from zesty (7.1.8-1ubuntu1) or later.

  [Regression Risk]
  TBD
