Implement test infrastructure for IPFS nodes

[jpraynaud]

Why

The IPFS PoC needs a hosted IPFS node on a test network to validate artifact upload and download in a realistic environment, beyond the local ipfs-devnet.

What

Provision and deploy the infrastructure to host the IPFS nodes used by the aggregator and the client on a test network.

How

• Define the infrastructure to host an IPFS node (compute, storage, network)
• Provision the IPFS node on the test network
• Expose the node API and gateway to the aggregator and the client
• Configure the aggregator and the client to use the deployed node
• Document the deployment and operation of the IPFS node
