lib/promscrape/discovery/kubernetes: propagate possible errors at newAPIWatcher() to the caller
This allows substituting FATAL panics with recoverable runtime errors such as missing or invalid TLS CA file
and/or missing/invalid /var/run/secrets/kubernetes.io/serviceaccount/namespace file.
Now these errors are logged instead of PANIC'ing, so they can be fixed by updating the corresponding files
without the need to restart vmagent.

This is a follow-up for 90427abc65

133b288681 lib/promscrape/discovery/kubernetes: use a single watcher per apiURL
Previously multiple scrape jobs could create multiple watchers for the same apiURL. Now only a single watcher is used.
This should reduce load on Kubernetes API server when many scrape job configs use Kubernetes service discovery.

43c39dc36c 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.
