Online GUI does not read Nginx vhost's client_max_body_size field from uploaded config file

[dsge]

Reproduce:

1. Have a working config.yaml that is using nginx
2. Upload it to puphpet.com
3. Find an nginx vhost
4. Set client_max_body_size to e.g. 512m from 1m
5. Download the modified config
6. Upload the modified config to puphpet.com
7. client_max_body_size is 1m instead of 512m

Example config.yaml:
