The webshell's pillar is being deployed in the shell role, but no nginx is deployed there so the webshell service is not working.

The provision script should:

#. Deploy the nginx's webshell vhost in a public facing node (workbench?)
#. Make sure the webshell's configuration points to the shell node and shellinabox port

(Checking in the clusters I have access to, webshell FQDN is never exposed to the user, being proxy-passed by nginx. Therefore, does webshell's FQDN be an internet FQDN/IP? Or is it enough to make it a private resource, for security sake?)
