Walletwasabi: [Feature] Improve logging to know from where blocks are downloaded

[NicolasDorier]

I configured Wasabi to connect to my own node.
However, I am confused: Why does wasabi try to connect to other peers at all?

So I checked the logs:

But the logs are not helpful at all to know if it works as expected.

The mempool is not yet received from Core, only the blocks.

Also transaction broadcasting happens to random nodes over Tor and over new Tor circuit. This however will not change unless Dandelion is implemented to Core. So we'll need P2P NBitcoin connection even if fully featured Core support is added.

Make sense. One day, I wish we can get a small windows where we can see which IP/TOR we are connected to so I can see if my connection to my Tor node is even working.

Clicking on the Peers can show this information in a new Tab.

Done with Bitcoin Core integration.
