v5

• Added LOG_LEVEL variable. Defaults to notice and accepts nginx error_log verbosity levels.

• HEALTHCHECK and STATS variables now accept location string instead of boolean value.

  Setting HEALTHCHECK=/health and STATS=/stats will create following config:

  server {
    listen 127.0.0.1:8080;
  
    access_log  off;
  
    location /stats {
      stub_status on;
    }
    location /health {
      return 200;
    }
    location / {
      return 404;
    }
  }
