71ea4935de lib/promscrape: add -promscrape.suppressDuplicateScrapeTargetErrors command-line flag in order to suppress duplicate scrape target errors 
Show also original labels for duplicate targets in error message in order to simplify debugging the issue.

Now `/targets` endpoint accepts optional `show_original_labels=1` query arg, which shows original labels for each target.
This may simplify debugging for target relabeling.

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

efc730863b 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,

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.
