Subject: [PATCH] nginx.conf: Use equal values for client_body_buffer_size and
 client_max_body_size to avoid writing big files to disk

Idea taken from https://medium.com/urban-massage-product/nginx-with-docker-easier-said-than-done-d1b5815d00d0 after noticing a user pushing a big layer
causing out of space errors writing to /var/cache/nginx.
