Separate nginx image is annoying

[agoncharov-reef]

I don't like having nginx outside of project repo. I think it's a bad idea:

1. The reason to have it outside of project is that we can update it in cookiecutter and thus update it on every project automatically, but we can update it via cruft update as well but manually, thus having more control over the process
2. It is rather ANNOYING that I don't have control over the nginx image, for example i've been hit twice already with letsencrypt configuration: there are cases when I want to intervent letsencrypt validation process and I cannot do that because
   nginx:
   image: 'ghcr.io/reef-technologies/nginx-rt:v1.0.0'
