Limit the number of outbound peer connections (#2944)
* Limit the number of outbound connections in the crawler

* Make zebra-network channel bounds depend on config.peerset_initial_target_size

* Bias Zebra towards outbound connections

And turn connection limits into `Config` methods.

* Downgrade some connection logs to debug

* Remove verbose or outdated fields in tracing logs

* Clarify connection limits

Includes:
- `fastmod OUTBOUND_PEER_BIAS_FRACTION OUTBOUND_PEER_BIAS_DENOMINATOR zebra*`
- clarify connection limit documentation

* Clarify inventory channel capacity

* Add zebra_network::initialize tests with limited numbers of peers

* Avoid cooperative async task starvation in the peer crawler and listener

If we don't yield in these loops, they can run for a long time before
tokio forces them to yield.

* Test the crawler with small connection limits

And use the multi-threaded runtime to avoid long hangs.

* Stop using the multi-threaded executor in tests where it's not needed

* Avoid starvation for every connection

Adds yields after inbound successes and initial peer connections.

* Add a crawler peer connection success test

* Add outbound connection limit tests

* Improve outbound tests
