Document the gitlab runners config
as per irc logs:
<alatiera> jjardon, do you we have the gitlab-runners configs anywhere? just curious
<jjardon> alatiera: no, we should though; can you open an issue in infra and assign it to me?
<alatiera> jjardon, sure thing
<jjardon> I'd like to keep them ansible but last time I took a look was not really worth the effort
