When updating the lab containing DSC configs, it seems that all config is reapplied regardless if it's necessary or not.

To speed up an update, the DSC config should be checked at each node first using Test-DscConfiguration -Path MOF-folder path.
Then apply the config if it doesn't match or can't be found.

Hi @DennisL68 - sounds like a great idea. I'll try and find some time to work on this module over the next week. My focus has recently been on updating the DSC community resources so haven't had any time to work on this module.
