Upgrade to 1.19.3.1

• Upgrade OpenResty to 1.19.3.1 (Upgrade to 1.19.3.1 #166)
• Added some documentation to nginx.conf file
• Added gitignore

Thank you for this PR! I'm testing it out and will push to CI soon.

I'm concerned with changing the worker_processes default. I just checked and the nginx image keeps it at 1. But we do handle some things differently as OpenResty is more of an application server. I appreciate wanting to be able to control this. I'm researching this more.

worker_processes

We can comment it out and open a new MR for it so it won't block the 1.19 release.

[neomantra]

I commented worker_processes out as the default is 1 anyway, and I'd prefer users set their own to an override.

That's pushed and on CI/CD. Once that is successful, I'll tag it and push.

This is building -- just Travis is really slow today.

Just found out that openresty/openresty:1.19.3.1-alpine-apk and openresty/openresty:1.19.3.1-alpine-amd64 differ in terms of shipped modules. E.g.. alpine-apk does not ship with the http_slice_module while alpine-amd64 does. Is this intended? Shouldn't they be interchangeable?

@fabiant7t Thanks helping verify the release! The alpine-apk is built from upstream OpenResty packages, whereas the alpine packages are built from source (BFS). The BFS flavors have different build options from the upstream flavors; there's an issue to harmonize that better. We try to keep the same as upstream modules and add sensible extras that people have requested over the years. So it makes sense that there might be an extra module.

It looks like upstream might have one arm64 pre-built package, but we haven't incorporated multi-architecture built-from-upstream Docker tooling.
