Uses webroot for obtaining certificate, avoids stopping jitsi-videobridge before obtaining certificate.
Adds a renew hook, where we reload apache or nginx and try to graceful shutdown jvb and restart it.
Before merging this we need to make sure graceful shutdown is enabled by default and also pubsub is enabled by default so after restarting jvb, jicofo will discover it.
The script looks for nginx, apache2 or jetty configuration and edits the first one found. Nginx and apache2 will be reloaded, while jvb will be stopped, configured and started again.
