We need more information about network usage

[b00f]

We should provide more information about the network usage, like:

• The number of bytes sent or received via gossip bundles We can also display this information separately for Consensus and General topics.
• The number of bytes sent or received via stream bundles
• The time when the node started
• The total number of connections the node has.

What information we can get from LibP2P? Probably we can have some comparison between actual data we consumed and actual data the LibP2P consumed.

@b00f we can already close this.
