grafana: multiple improvements to the dashboard (#864)

Co-authored-by:  Orsiris de Jong <ozy@netpower.fr>

This PR obsoletes https://github.com/zrepl/zrepl/pull/847.

Changes:

* Rearrange dashboard into sections sections: About, Top, Replication,
Internals.
* consistently force selection of a single prom_job_name (no more
multi-value)
* Replace the repeated Gauge panel for failed replications with a
'status history' panel.
* Use `zrepl_start_time` as the metric underlying the `prom_job_name`
variable.
* Replace `zrepl_job_name` with internal dashboard variable
`zrepl_replication_jobid` and use that _only_ in the `Replication`
section of the dashboard
* Update to Grafana v12.4
