  [SRU] NetworkManager parser: ip-tunnel connections fail

Bug description:
  
  [Impact] 

   * NetworkManager snap (using the netplan backend) fails to add "ip-
  tunnel" connections.

   * ip-tunnel connections are needed in UC20 via the NetworkManager
  netplan integration

   * This upload includes an upload commit that uses netplan's
  "passthrough" mode to handle ip-tunnel connections, so all settings
  can be stored correctly.

  [Test Plan]

  Using NetworkManager with the netplan backend integration (e.g. network-manager snap from the 20/stable channel) one can launch "nmtui" and then:
  - Proceed to edit -> add new connection
  - Select "IP tunnel"
  - enter a profile name e.g. "IP tunnel connection 1"
  - enter a device e.g. "gre10"
  - select mode "GRE"
  - enter local IP e.g. "10.20.20.1"
  - enter remote IP e.g. "10.20.20.2"
  - Press "OK" to save the connection

  This should NOT yield the following error message, but return
  successfully:

  "Unable to add new connection: failure adding connection: keyfile
  writer produces an invalid connection: cannot access file: No such
  file or directory"

  - run "netplan get nm-devices" to confirm the connection was created successfully, using passthrough configuration
  - run "nmcli c show" to confirm the new connection has been picked up by NM, too

  [Where problems could occur]

   * This upload touches netplan's NetworkManager keyfile parser code.
  So if something is broken this could impact the NetworkManager netplan
  backend integration.

  [Other Info]
   
   * Additionally we will run and verify the usual autopkgtests once the package got accepted into -proposed
