Add user warcall22.

One of three users in the group project.

This user already requested via the webpage, but I was already here so I minus well do it here.

I am not really familiar with ansible, so I don't know if ``createhome`` is a required item, but I selected no, as these users do not need their own home directory, they merely need access to the shared one. 

I also copied in the pubkey, so I do not know if the formatting it brought over is correct... 
Here is a link to the pubkey in case... https://pastebin.com/9MhLc4Rd
