Fix join errors in initial seed peer versions dashboard (#2811) 
* Add metrics gauges for the most recent peer network protocol version

This gague lets us join the initial seeds to the network protocol versions,
even if the peer upgrades and reconnects with a different version.

* Ensure dashboard peer network versions are unique

Otherwise, prometheus returns an error,
and the dashboard shows no data.

* Make seeder labels more readable

- put labels to the right of the graph
- remove default ports

Provide recent syncer response lengths as a watch channel (#2602) 
* Minimal recent sync lengths implementation

Also includes metrics and logging, to make diagnosing bugs easier.

* Add logging to check what happens when Zebra reaches the chain tip

* Add tests for recent sync lengths

- initially empty
- pruned to correct length
- newest entries go first

* Drop a redundant `/` from a Cargo.lock URL

This seems to be a nightly or beta Rust change,
but hopefully stable just accepts it.

* Use metrics histograms to avoid overwriting values

* Add detailed syncer monitoring dashboard

* Increase the recent sync length to 4

This length makes it easier to distinguish between temporary and
sustained errors/syncs.

Jack Grigg e51f33a4b9 Use interoperable names for common metrics 
These names match the equivalent metrics in zcashd, enabling common
metrics to be collected across both node types.
