Remove async registration of apiWatchers, since it breaks discovering `role: endpoints` and `role: endpointslices` targets,
which depend on pod and service objects.
There is no need in reloading `endpoints` and `endpointslices` targets if the referenced `pod` or `service` objects change,
since in this case the corresponding `endpoints` and `endpointslices` objects should also change because they contain
ResourceVersion of the referenced `pod` or `service` objects, which is modified on object update.

...
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

vendor: use github.com/VictoriaMetrics/fasthttp instead of github.com/fasthttp/fasthttp
...
The upstream fasthttp may contain issues like 996610f021
,
plus a code that isn't used by VictoriaMetrics. So let's use a private copy under our control instead.
