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

b6d88bac04 vendor: use github.com/VictoriaMetrics/fasthttp instead of github.com/fasthttp/fasthttp

plus a code that isn't used by VictoriaMetrics. So let's use a private copy under our control instead.
