Implement IPFS default to local and fallback on remote #2275
Description
In the toolkit submodule, allow defining multiple IPFS gateway URLs. Always use the first one provided to start fetching the content and keep moving to the next gateway url if there is an error.
Since the URL are from IPFS gateway, use the exposed enpoint to verify first if in any of the gateway URL is present the content of the ipfs cid to be retrieved. Check official documentation from https://docs.ipfs.tech/reference/http/gateway/
Implement in the index in the dappmanager module the initialization of the instance with the ipfs gateway URLs
