- Remove unused js bloatware from /targets page. This strips down binary size by more than 100Kb
- Add /service-discovery page for API compatibility with Prometheus
- Properly load bootstrap.min.css from /prometheus/targets
- Serve static contents for /targets page from app/vminsert instead of app/vmselect, because /targets page is served from there
The default size of `indexdb/tagFilters` now can be overridden via
`storage.cacheSizeIndexDBTagFilters` flag.
Please, be careful with changing default size since it may
lead to inefficient work of the vmstorage or OOM exceptions.

* lib/promscrape/discovery/kubernetes: properly updates discovered scrape works
previously, added or updated scrapeworks may override previuosly
discovered.
it happens because swosByKey may contain small subset of kubernetes
objects with it's labels.
It happens for objectsUpdated and objectsAdded maps, which include only changed elements
* Properly calculate vm_promscrape_discovery_kubernetes_scrape_works

docs: update docs for beginners
QuickStart page was updated with more relevant information.
Key Concepts was added to cover basics for the VictoriaMetrics.
Unexpectedly, Grafana makes an extra request to `/rules`
handler in addition to `/api/v1/rules` calls in alerts UI.
This happens only for Grafana versions older than 8.5.*.
Apparently, this is related to support of other monitoring
systems.
Prometheus responds with `text/html` content for UI page `/rules`
to such requests. Actually, returning just a blank page with
SC=200 works as well.
Returning actual response of `/api/v1/rules`
results in error in Grafana since it expects a `yaml` (?) in response.
So we add a placeholder to `vmalert`.

For liquid text processor double braces `{{` `}}`
are special chars for templating.
Since we use them in some of our docs with different purpose,
we must escape them to avoid syntax errors from liquid.
For escaping curly braces we use bult-in plugin which helps
to enclose sections of text via `{% raw %}` and `{% endraw %}`.
This approach prevents liquid syntax errors and makes render correct.
