Updates to GPG key request for networks with firewalls.

I had some issues with the vvv vagrant up when provisioning becuase our firewall doesn't allow many ports. 

This updates the gpg key request to use hkp://keyserver.ubuntu.com:80 per the answer found here http://unix.stackexchange.com/a/110594/82971

I also added some redirection for output to avoid the red text shown warning that he configuration will not be available right now. That cuts back on the red text mentioned in #229.
