936fb0eac3 app/vmagent/remotewrite: retry sending data if the server closes keep-alive connection 
This should fix the following error when sending data to remote storage:

couldn't send a block with size XX bytes to "YYY": the server closed connection before returning the first response byte. Make sure the server returns 'Connection: close' response header before closing the connection

067c7afebc lib/promscrape: show information on improperly configured scrape targets at the bottom of /targets page
