refactor: examples/delegated-routing

[vasco-santos]

This PR refactors the delegated-routing example to the refactored async js-libp2p.

[vasco-santos]

We need to get libp2p to js-ipfs before getting this to work.

However, I could also not test this with #master . Do we need to run go-ipfs in the specific branch mentioned in the README?

There are some configuration issues that need to be resolved, see #371 (review).

In regards to requiring ipfs, we may want to revisit this example and only have libp2p in the client. The example cats a file right now, but in reality we just need to find things on the network via the delegate node.

[vasco-santos]

For this example, should we have a js-libp2p node running and providing a few cid that we can then find with the app example?

[achingbrain]

Is this necessary? js-ipfs doesn't have a runtime dependency on eslint? Maybe if this example was in the js-ipfs repo?

[vasco-santos]

This is needed. I copied this from the react example of js-ipfs, but did not read the comment: https://github.com/ipfs/js-ipfs/blob/master/examples/browser-create-react-app/.env
It is aegir that installs a version of webpack that is not compatible with react-scripts. I am going to change that comment

[vasco-santos]

After syncing with @jacobheun , we will start by having a public delegated router configured.

We were having some issues finding peer via the delegate because of the lack of support for HTTPS in the go-ipfs API. This needs to be properly configured using a reverse proxy and generated SSL certificates. I will create an issue to track adding documentation for infrastructure for going to production to unblock this PR for now.
