During background downsampling, rate(vm_deduplicated_samples_total{type="merge"}) could be much bigger than
rate(vm_rows_added_to_storage_total) and it could last quite some time,
which causes negative values of Storage full ETA and confuses users, see playground.
Instead of trying to get more accurate results during downsampling, I think it's ok to ignore
vm_deduplicated_samples_total at all, it's more reasonable to see Storage full ETA increase after downsampling.

It should help identifying cases when too much CPU is spent on garbage collection,
and advice users on how this can be addressed.

* add panels for detailed visualization of traffic usage between vmstorage, vminsert, vmselect
components and their clients. New panels are available in the rows dedicated to specific components.
* update "Slow Queries" panel to show percentage of the slow queries to the total number of read queries
served by vmselect. The percentage value should make it more clear for users whether there is a service degradation.

The `path!="/favicon.ico"` filter has little sense, since there are many other special paths,
which may be filtered out - /metrics, /flags, /health, /ping, /robots.txt, /-/healthy, /-/ready, /reload, etc.
See /lib/httpserver/httpserver.go for more details.
It will be hard or impossible to maintain filters for all these paths, so it is better to drop this filter
in order to simplify queries and improve the consistency of these queries.
`version` label won't show the difference if various flavors of the same
version were deployed. But `short_version` will.
For example, on the sandbox env we test VM builds before new version release.
Without this change, the version update won't be visible on dashboard.

Fix vminsert/vmstorage/vmselect metrics filtering when dashboard is used
to display data from many sub-clusters with unique job names.
Before, only one specific job could have been accounted for component-specific panels,
instead of all available jobs for the component.
