ingress-nginx Support LUA to fetch TLS certificates for TCP/UDP stream listeners

Currently LUA logic to fetch certificates is supported only for HTTPS listeners:

https://github.com/kubernetes/ingress-nginx/blob/8b2db80433ac653bc5c98bffaa863e619c5563c0/rootfs/etc/nginx/template/nginx.tmpl#L892-L899

Having a ssl_certificate_by_lua_block block in stream section would be appreciated.

/kind feature

@aledbf could you please estimate this task? Quick fix doesn't work, since certificate.lua requires resty.http, which cannot be imported in the stream nginx section.

Is there a workaround, manually specifying the paths to the certificates? I suspect they are not mounted, but loaded directly from secrets into memory via that lua script
