since this recently comes up more often here, i quickly threw together a snap:

name: reboot-test
base: core20
version: '0.1' # just for humans, typically '1.2+git' or '1.3.2'
summary: Single-line elevator pitch for your amazing snap # 79 char long summary

  This is my-snap's description. You have a paragraph or two to tell the
  most important story about your snap. Keep it under 100 words though,
  we live in tweetspace and your description wants to look good in the snap
  store.

grade: stable
confinement: strict

apps:
  reboot:
    command: usr/bin/reboot
    environment:
      PYTHONPATH: $SNAP/usr/lib/python3/dist-packages:$PYTHONPATH
    plugs:
      - shutdown

parts:
  reboot:
    plugin: dump
    source: .
    organize:
      reboot.py: usr/bin/reboot
    stage-packages:
      - python3-dbus

and the reboot.py script:

#! /usr/bin/env python3

import dbus

bus = dbus.SystemBus()
bus_object = bus.get_object("org.freedesktop.login1", "/org/freedesktop/login1")
bus_object.Reboot(True, dbus_interface="org.freedesktop.login1.Manager")

calling it as: sudo reboot-test.reboot will then reboot your system …
