Get rid of all defaults for variables.

[boatrite]

Instead, generate a file with all of them (group_vars/all probably?).

A more unixy thing might be to generate that file and have actual defaults but the file have all the commented ones?

What prompted this was Brett found out subspace defaults to 16 puma threads and a db connection of 5. Being more clear about our defaults I believe is the goal.

I think it would be nice for pseudo documentation too. It also seems bad to have to open the subspace repo to see something a simple as how many puma workers/threads you have on a server. It's nice to have good defaults but it might be nicer to know for certain how production is configured at a glance.
