c3c3e51f17 docs/vmalert.md: remove misleading -evaluationInterval=3s from example config args
3s evaluation interval is too small for practical setups. It can result in increased load on datasource.
So it is better to remove it from example config args, which are usually copy-pasted by novice users.

904dababcc vendor: update github.com/VictoriaMetrics/metrics from v1.15.3 to v1.16.0
This adds the following new metrics for each VictoriaMetrics app:

* process_resident_memory_anonymous_bytes - the RSS share for memory allocated by the process itself.
  This share cannot be freed by the OS, so it must be taken into account by OOM killer.

* process_resident_memory_pagecache_bytes - the RSS share for page cache memory (aka memory-mapped files).
  This share can be freed by the OS at any time, so it must be ignored by OOM killer.

Per-scrape limit on number of scraped samples that will be accepted.
If more than this number of samples are present after metric relabeling
the entire scrape will be treated as failed. 0 means no limit.

17b87725ed lib/promscrape/discovery/kubernetes: reduce memory usage when Kubernetes service discovery is configured on a big number of scrape jobs
Previously vmagent was creating a separate Kubernetes object cache per each scrape job.
This could result in increased memory usage when monitoring a Kubernetes cluster with big number of objects (pods / nodes / services, etc.)
as seen at https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1113

Now it uses a shared map of scrape objects across multiple scrape jobs.
