Title:
  netplan apply will crash if openvswitch is not running

Status in netplan.io package in Ubuntu:
  Fix Released

Bug description:
  The problem was reported on Ubuntu 22.04.

  netplan apply will call ovs-vsctl and will crash if openvswitch is not running.
   

  # sudo netplan apply
  ovs-vsctl: unix:/var/run/openvswitch/db.sock: database connection failed (No such file or directory)
  Traceback (most recent call last):
    File "/usr/sbin/netplan", line 23, in <module>

    File "/usr/share/netplan/netplan/cli/ovs.py", line 138, in apply_ovs_cleanup
      out = subprocess.check_output([OPENVSWITCH_OVS_VSCTL, '--columns=name,external-ids',
    File "/usr/lib/python3.10/subprocess.py", line 420, in check_output
      return run(*popenargs, stdout=PIPE, timeout=timeout, check=True,
    File "/usr/lib/python3.10/subprocess.py", line 524, in run
      raise CalledProcessError(retcode, process.args,
  subprocess.CalledProcessError: Command '['/usr/bin/ovs-vsctl', '--columns=name,external-ids', '-f', 'csv', '-d', 'bare', '--no-headings', 'list', 'Port']' returned non-zero exit status 1.


  Netplan should throw a warning message and ignore ovs configuration is
  cases like this.
