  By specifying configuration at CRD, operator generates config for `VMAgent` and syncs it. It's possible to use static targets

 The `VMNodeScrape` CRD provides discovery mechanism for scraping metrics kubernetes nodes.

 ## VMStaticScrape
 
 The `VMStaticScrape` CRD provides mechanism for scraping metrics from static targets, configured by CRD targets.
 By specifying configuration at CRD, operator generates config for `VMAgent` and syncs it. It's useful for external targets management,
 when service-discovery is not available. `VMAgent` staticScrapeSelector must match `VMStaticScrape` labels.
