OCPBUGS-14123: make TestBodySizeLimit less flaky

[raptorsun]

TestBodySizeLimit checks Prometheus config file instead of the metric "prometheus_target_scrapes_exceeded_body_size_limit_total".

The package "github.com/prometheus/prometheus/discovery/kubernetes" is added to vendor/ to parse the field kubernetes_sd_configs in the config file.
