Simplify ipfs gateway and api setup

[fbielejec]

ipfs-server service is not necessary, It can be achieved with the nginx-proxy as vhost rules.

Implementation

Write the rules from:
https://github.com/district0x/ipfs-docker/blob/master/server/ipfs.server

into specifs ipfs host config files (one for QA and one for production).

Closing as too complex. The upstream blocks would need to be in a custom default nginx.conf, rewrite rules in host specific files and location blocks also in specific host _location files, this multipled by all environment. It's cleaner to maintain a specific server service
