Bug description:
  [SRU] 2.68.3:
  https://bugs.launchpad.net/ubuntu/+source/snapd/+bug/2098137

  [ Impact ]

  Addition of block devices (ACTION=="add", SUBSYSTEM=="block") trigger snapd provided udev rule `udev/rules.d/66-snapd-autoimport.rules`, not intended
  or required for classic systems, causing unwanted errors like `Process '/usr/bin/unshare -m /usr/bin/snap auto-import --mount=/dev/nvme0n1' failed with exit code 1`

  [ Test Plan ]

  1. Produce error with snapd 2.66.1 deb

  insert usb storage
  journalctl -b | grep 'exit code 1'
  expect to find '/usr/bin/unshare -m /usr/bin/snap auto-import --mount=/dev/sdb' failed with exit code 1

  2. Change to snapd 2.68.3 deb

  insert and remove usb storage multiple times
  journalctl -b | grep 'exit code 1'
  should not find any new entries

  Repeat for all targeted Ubuntu releases.
