xp_cmdshell Restore Service to Identified State

[Zamanry]

My team uses msdat non-interactively against a ton of machines using GNU's parallel command. We like to check and see if xp_cmdshell can be executed. Currently xp_cmdshell allows the user to enable or disable the xp. However, I'd like to be able to restore the xp_cmdshell to how we found it so that I am not leaving xp_cmdshell enabled if was already disabled on client environments.

So the breakdown would be:

1. If xp_cmdshell is disabled and can be enabled:
   1. Enable
   2. Execute
   3. Disable
2. If xp_cmdshell is enabled:
   1. Execute
