VRL: add main log format for parse_nginx_log

[virtualtam]

Use Cases

The parse_nginx_log function currently supports the following formats:

• combined
• error
• ingress_nginx

The official Docker images for Nginx come with a default configuration file using the main format, defined as:

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

Reference

These configuration files are provided by the Nginx Linux Packages repositories, and the corresponding source packages are located in the pkg-oss repository:

• alpine/alpine/nginx.conf
• debian/debian/nginx.conf
• rpm/SOURCES/nginx.conf
