ci/ci-test.sh leaves generated resources present in system.

[kro-cat]

Describe the problem/challenge you have a successful or unsuccessful run of ci/ci-test.sh leaves the temporary file /tmp/disk.img, a loopback device /dev/loopN, and a volume group lvmvg present on the host. This may be an issue when running ci tests locally.

Describe the solution you'd like Add an exit handler to ci/ci-test.sh which cleans up generated resources from the system:

sudo pvcreate "$disk"
sudo vgcreate lvmvg "$disk"

# --------------------  Addition --------------------
# Clean this stuff up on termination
cleanup() {
  echo "Exiting: Cleaning up test resources"
  sudo vgremove lvmvg
  sudo pvremove "$disk"
  sudo losetup -d "${disk}"
  rm /tmp/disk.img
}
trap cleanup EXIT
# -------------------- /Addition --------------------

# install snapshot and thin volume module for lvm
sudo modprobe dm-snapshot

Environment:

• LVM Driver version: 2.03.22(2) (2023-08-02)
• Cloud provider or hardware configuration: Local development machine
• OS (e.g. from /etc/os-release): Arch Linux

Any tests for issue #247 will most likely involve modifying the ci-test.sh script, so I might wind up combining this with the PR for that one.
