  Slow startup with zram-config installed (/dev/zram0) or encrypted swap

Bug description:
  Ubuntu 18.04 startup slowdowns for 30-60 seconds when zram-config installed or swap is encrypted.
  When generating initrd I get this message in terminal:

  I: The initramfs will attempt to resume from /dev/zram0
  I: (UUID=e380356c-767e-4265-98da-8be62ad28569)
  I: Set the RESUME variable to override this.###########################################.................] 

  So the local-premount script in initramfs was waiting for a swap
  device that was not available, until it timed out. The relevant
  message was gave up waiting for suspend/resume device.

  To disable this (as resuming from swap is not possible with an
  encrypted swap, and I don't use hibernation anyway), I modified this
  file: /etc/initramfs-tools/conf.d/resume. In this file, a line with
  RESUME=none (instead of the UUID that was here) will disable waiting
  for a resume device.

  Run sudo update-initramfs -u to apply the changes.

  Please, fix it already. Duplicate of Bug #1768230 on Ubuntu 18.10
