vmalert: set alert's source link to UI instead of JSON source ( #2986 )
...
We switch default alert's source link to redirect user
to vmalert's UI instead of previous JSON object. While it breaks
compatibility, it also supposed to improve user's experience.
The old behavior can be achieved by updating `-external.alert.source`
command-line flag.

lib/promscrape: automatically generate additional per-target labels for targets with non-zero series limit

The following metrics are generated:
- scrape_series_limit

These metrics simplify alerting on targets, which expose too many time series
See https://docs.victoriametrics.com/vmagent.html#automatically-generated-metrics

The 429 status code means that the server is overwhelmed with requests.
The client can retry the request after some wait time.
Implement this strategy for service discovery and scrape requests.

app/vmselect/netstorage: improve scalability of blocks processing on systems with multiple CPU cores
...
Previously a single syncwg.WaitGroup was used for tracking the lifetime of processBlock callbacks
across all the per-vmstorage goroutines. This could be slow on systems with many CPU cores
because of inter-CPU synchronization overhead.
Use a separate per-vmstorage sync.WaitGroup instead in order to reduce inter-CPU synchronization overhead.
This should imrpove performance for heavy queries over big number of blocks on multi-CPU systems.
