metrics to be collected across both node types.

teor e50692bd51 CandidateSet: Add Listener Port Connections 
Inbound connections on the Zcash protocol listener port
perform a handshake. If the handshake is successful, it
adds the peer to the AddressBook.

Fix a peer DNS resolution edge case (#1796) 
* Retry each peer DNS a few times individually

We retry each peer individually, as well as retrying if there are no
peers in the combined list.

DNS failures are correlated, so all peers can fail DNS, leaving Zebra
with a small list of custom-configured IP address peers.

Individual retries avoid this issue.

* Rename parse_peers to resolve_peers

teor e06705ed81 Only reject pending client requests when the peer has errored 
- Add an `ExitClient` transition, used when the internal client channel
  is closed or dropped, and there are no more pending requests
- Ignore pending requests after an `ExitClient` transition
- Reject pending requests when the peer has caused an error
  (the `Exit` and `ExitRequest` transitions)
- Remove `PeerError::ConnectionDropped`, because it is now handled by
  `ExitClient`. (Which is an internal error, not a peer error.)

Diagnostics for CI port conflict failures (#1766) 
Log a "Trying..." message before each listener opens, to see if the
delay is inside Zebra, or in the test harness or OS.

Also report the configured and actual ports where possible, for better
diagnostics.

Fix candidate set address state handling (#1709) 
Design:
- Add a `PeerAddrState` to each `MetaAddr`
- Use a single peer set for all peers, regardless of state
- Implement time-based liveness as an `AddressBook` method, rather than
  a `PeerAddrState` variant
- Delete `AddressBook.by_state`

Implementation:
- Simplify `AddressBook` changes using `update` and `take` modifier
  methods
- Simplify the `AddressBook` iterator implementation, replacing it with
  methods that are more obviously correct
- Consistently collect peer set metrics

Documentation:
- Expand and update the peer set documentation

We can optimise later, but for now we want simple code that is more
obviously correct.
