  1. libplugin: pay now emits channel_hint as we learn about the net 

    The `pay` plugin, as well as other plugins making use of the tree-pay
executor, will now emit their observations as they see them. The
notifications are sent on the `channel_hint_updated` topic, and any
subscriber will get them.

We also added a `timestamp` to the `struct channel_hint`, as these
observations now outlive the `pay` call, and have to be attenuated /
relaxed as they age, until we can eliminate them completely (when the
restriction is equal to the structural information gathered from the
gossip).

Changelog-Added: pay: Payments now emit `channel_hint_updated` notification to share inferred balances and observations across multiple payments.
