** Description changed:

+ [Impact]
+ Netplan users who use the NetworkManager backend (ie. all desktop users);
+ only when NetworkManager 1.15.2 is in use (disco and higher).
+ 
+ [Test case]
+ 1) Apply any currently working configuration.
+ 2) Run 'netplan apply'
+ 3) Verify that the files generated in /run/NetworkManager/system-connections/ include a ".nmconnection" suffix.
+ 
+ [Regression potential]
+ None; this additional extension allows support for NetworkManager 1.15.2 and has additional effect on earlier version of NetworkManager: files are parsed despite any possible file suffix.
+ 
+ ---
+ 
  NetworkManager 1.15.2 or later (as included first in Ubuntu 19.04 Disco Dingo) now requires that files in /{etc,run}/NetworkManager/system-connections end in the suffix '.nmconnection' as per the following commit:
  https://github.com/NetworkManager/NetworkManager/commit/648c256b9014198aac388097e410999c68c4b452
  
  NetPlan writes files as /run/NetworkManager/system-connections/{name}
  without any suffix. On Ubuntu 19.04 these files are ignored and the
  configuration is not applied.
  
  If you rename the files to end in '.nmconnection' then you can see the
  interface configuration loaded by NetworkManager.
  
+ root at optane:/run/NetworkManager/system-connections# ls
+  netplan-eno1   virbr0.nmconnection  'Wired connection 1.nmconnection'  'Wired connection 2.nmconnection'
  
- root at optane:/run/NetworkManager/system-connections# ls
-  netplan-eno1   virbr0.nmconnection  'Wired connection 1.nmconnection'  'Wired connection 2.nmconnection'
- 
- root at optane:/run/NetworkManager/system-connections# cat /etc/netplan/03-netcfg.yaml
