Graph integration

PRODUCT TASK

What to do?

We need to integrate the list of subgraphs for apps in our marketplace on Gnosis
It'll be an experiment with the limited list of dapps on our side, so we need to devise an approach to store this list of subgraphs. I think the best approach is to store this mapping in Github in the following format:

[
  {
    "appId": "balancer",
    "chainsData": [
      {
        "chainId": 100,
        "links": ["url1", "url2"]
      },
      {
        "chainId": 8453,
        "links": ["url1", "url2"]
      }
    ]
  },
  {
    "appId": "aave",
    "chainsData": [
      {
        "chainId": 1,
        "links": ["url1", "url2"]
      },
      {
        "chainId": 10,
        "links": ["url1", "url2"]
      }
    ]
  }
]
