lib/promscrape/discovery/kubernetes: use v1 API instead of v1beta1 API for role: ingress and role: endpointslices

Browse Source 
This should fix service discovery for these roles in Kubernetes v1.22 and newer versions.
See https://kubernetes.io/docs/reference/using-api/deprecation-guide/#ingress-v122

* FEATURE: vmagent: add ability to read scrape configs from multiple files specified in `scrape_config_files` section. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1559). * FEATURE: vmagent: add ability to read scrape configs from multiple files specified in `scrape_config_files` section. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1559).
* FEATURE: vmagent: reduce memory usage and CPU usage when Prometheus staleness tracking is enabled for metrics exported from the deleted or disappeared scrape targets. * FEATURE: vmagent: reduce memory usage and CPU usage when Prometheus staleness tracking is enabled for metrics exported from the deleted or disappeared scrape targets.
* FEATURE: vmagent: discover `role: ingress` and `role: endpointslice` in [kubernetes_sd_config](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#kubernetes_sd_config) via v1 API instead of v1beta1 API if Kubernetes supports it. This fixes service discovery in Kubernetes v1.22 and newer versions. See [these docs](https://kubernetes.io/docs/reference/using-api/deprecation-guide/#ingress-v122).
* FEATURE: take into account failed queries in `vm_request_duration_seconds` summary at `/metrics`. Previously only successful queries were taken into account. This could result in skewed summary. See [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/1537). * FEATURE: take into account failed queries in `vm_request_duration_seconds` summary at `/metrics`. Previously only successful queries were taken into account. This could result in skewed summary. See [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/1537).
* FEATURE: vmalert: add `-disableAlertgroupLabel` command-line flag for disabling the label with alert group name. This may be needed for proper deduplication in Alertmanager. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1532). * FEATURE: vmalert: add `-disableAlertgroupLabel` command-line flag for disabling the label with alert group name. This may be needed for proper deduplication in Alertmanager. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1532).
* FEATURE: update Go builder from v1.16.7 to v1.17.0. This improves data ingestion and query performance by up to 5% according to benchmarks. See [the release post for Go1.17](https://go.dev/blog/go1.17). * FEATURE: update Go builder from v1.16.7 to v1.17.0.
