Lock execution result and test cases in zephyr Scale.

OK.  So, there's no 'lock' feature as such but there is a permissions setting on who can execute test cycles and maybe that could help but I'm not sure if it would work and if it did it could take some work to make it work!

The ideas portal is currently being migrated onto a new platform, but I recall seeing this as a feature request - ideally we just need a padlock icon that we can click on and off.
