114cf24b43 lib/promscrape/discovery/dns: add __meta_dns_srv_record_target and __meta_dns_srv_record_port labels

af994562c8 Added endpointslices discovery to k8s api (#760) 
This is similar to https://github.com/prometheus/prometheus/pull/6838 , which will be added in Prometheus v2.21.
See https://github.com/prometheus/prometheus/releases/tag/v2.21.0-rc.1

* Added endpointslices discovery to k8s api

Started from 1.17 k8s version endpointslices is beta,
it allows to query k8s api for endpoints more efficient.
It presents at scrape_config.yaml as separate role for kubernetes_sd_config.
kubernetes_sd_config:
- role: endpointslices

* fixed typos, changed EndpointConditions signature - with values instead of pointers

95ce89e7d7 lib/promscrape: use the number of parsed rows as a basis for writeRequestCtxPool leveling 
The previous basis on `cap(sw.labels)` doesn't work anymore after 7785869ccc ,
because `sw.labels` may be reset multiple times when processing big number of rows.

9a77ae9d1c lib/promscrape: reduce memory usage when scraping targets with big number of metrics alongside targets with small number of labels 
Previously targets with big number of metrics and/or labels could generated too big buffers,
which then could be re-used when scraping targets with small number of metrics.
This resulted in memory waste.

Now big buffers are used only for targets with big number of metrics / labels,
while small buffers are used for targets with small number of metrics / labels.

a02097e657 Extend metric vm_promscrape_targets with status label (#615) 
The change to `vm_promscrape_targets` metric suppose to improve observability
for `vmagent` so it will be possible to track how many targets are up or down
for every specific scrape group:
```
vm_promscrape_targets{type="static_configs", status="down"} 1
vm_promscrape_targets{type="static_configs", status="up"} 2

f58d15f27c lib/promscrape: rename 'scrape_config->scrape_limit' to 'scrape_config->sample_limit' 
`scrape_config` block from Prometheus config contains `sample_limit` field,
while in `vmagent` this field was mistakenly named as `scrape_limit`.

bf1869d33d lib/promscrape: allow overriding external_labels as Prometheus does 
Prometheus docs at https://prometheus.io/docs/prometheus/latest/configuration/configuration/#scrape_config say:

> In communication with external systems, they are always applied only
> when a time series does not have a given label yet and are ignored otherwise.

Though this may result in consistency chaos when scrape targets override `external_labels`,
let's stick with Prometheus behavior for the sake of backwards compatibility.

There is last resort in vmagent with `-remoteWrite.label`, which consistently
sets the configured labels to all the metrics before sending them to remote storage.

d39dd8aa69 lib/promscrape: do not retry idempotent requests when scraping targets 
This should prevent from the following unexpected side-effects of idempotent request retries:
- increased actual timeout when scraping the target comparing to the configured scrape_timeout
- increased load on the target
