app/vmselect: abort streaming connections for vmselect (#5650) 
* app/vmselect: abort streaming connections for vmselect
due to streaming nature of export APIs, curl and simmilr tools cannot
detect errors that happened after http.Header with status 200 was
written to it.

This PR tracks if body write was already started and closes connection.

It allows client to detect not expected chunk sequence and return error
to the caller.

Mostly it affects vmselect at cluster version

docs: remove slug from Grafana dashboard URLs 
Each Grafana dashboard has unique ID which can be used to fetch the dashboard
from grafana.com: https://grafana.com/grafana/dashboards/11176
The same dashboard can be accessed via URL with slug: https://grafana.com/grafana/dashboards/11176-victoriametrics-cluster/
But using slug implies that any change to dashboard name will break the link.
So it is better to just use ID, so the dashboard URL will never break.

This is follow-up for ff33e60a3d

docs/setup-size: rm tolerable churn rate % 
It is likely this value was borrowed from panel `Slow inserts` panel
from Grafana dasbhoard for VM single/cluster installations. This is a mistake.
There is no such thing as "tolerable churn rate", as tolerancy depends on the amount
of allocated resources.

Although, it is unclear what is meant by 5%. If it refers to 5% of new time series per second,
then such churn rate is extremely high. It would mean that the avg life of a time series is 20s.

lib/storage: follow-up for 4b8088e377 
- Clarify the bugfix description at docs/CHANGELOG.md
- Simplify the code by accessing prefetchedMetricIDs struct under the lock
  instead of using lockless access to immutable struct.
  This shouldn't worsen code scalability too much on busy systems with many CPU cores,
  since the code executed under the lock is quite small and fast.
  This allows removing cloning of prefetchedMetricIDs struct every time
  new metric names are pre-fetched. This should reduce load on Go GC,
  since the cloning of uin64set.Set struct allocates many new objects.
