deploy nginx rate limiting

[martenson]

to minimize Dos surface

from Nate:

It's probably not a bad idea
galaxyproject/infrastructure-playbook@ae88e63
We could do this for Galaxy as well
We already added one for collections but I suspect there'd be no downside to just applying it for all of Galaxy: https://github.com/galaxyproject/infrastructure-playbook/blob/main/templates/nginx/usegalaxy_proxy.conf.j2#L48

I don't understand what it actually does, nor how it works. We could discuss this in person.

[martenson]

@martindemko which part? It mostly just limits how many requests will be served over a period of time and gives you fast HTTP 429 if client does requests too fast.

[martindemko]

All of it. Thanks for explaining to me, Nginx settings was and remains a big mystery to me :D
