Adding Specific ExitNodes

[hatemjaber]

Hi, I was wondering if there is a mechanism in place to allow specifying the exit node:

ExitNodes {us} StrictNodes 1

I could not find anything in the documentation or in the code that indicated an environment variable etc... to allow you to set the value for this. I would be willing to contribute the change if you can direct me to where it should be added. I looked through the code and it would require a deeper dive to get my head wrapped around it enough to figure out what's going on.

Thank you in advance!
