Announce right addresses and CORS

[simonovic86]

• announce reachable addresses (load balancer, etc)
• add CORS parameters to the IPFS HTTP API
• fix tsconfig.json
• rename IPFS_API_ONLY to IPFS_ENABLE_API (default=true)
• rename IPFS_GATEWAY_ONLY to IPFS_ENABLE_GATEWAY (default=true)
• fix IPFS dependency issue

lgtm. This just enables the ipfs instance to announce the correct address right?

It also adds CORS parameters to the IPFS HTTP API and renames flags.
