Update systemd configs to start at boot time

The current configurations won't start vouch-proxy after a system reboot

@woneill thanks for the contribution

Is there a reason not to use the default runlevel?

[woneill]

@bnfinet To be honest, I'm not sure! I changed it based on the other systemd configs I saw on our system.

I looked into what the difference is between default.target and multi-user.target was. It sounds like default.target is usually an alias for either graphical.target or multi-user.target so that change might not be needed.

@woneill thanks for checking..

I'm not sure who might be running VP on their laptop but I bet they're out there. :)

With that adjustment I'm happy to merge.

@bnfinet Thanks for the merge! I'm sorry I misunderstood that you were asking for me to update the runlevel- I've come across Xwindows running on rackmounted servers so I don't discount what kinds of crazy things people do :)
