Add provisioning script

Alright, so I didn't see this coming, but it turns out because of the way I have my ansible-pull script set up, I can just lay it out on a host and it'll git pull and manage the rest itself
I'm like 'why is this thing taking so long to deploy', and it's because it's deploying twice

provision.yml
