new feature: debug relabeling (#1344) 
* new feature: relabel logging

Use scrape_configs[x].relabel_debug = true to log metric names inkl.
labels before and after relabeling. After relabeling related metrics
get dropped, i.e. not submitted to servers.

* vminsert wants relabel logging, too.

364f30a6e7 lib/promscrape: store ScrapeWork items by pointer in the slice returned from get*ScrapeWork() 
This should prevent from possible 'memory leaks' when a pointer to ScrapeWork item stored in the slice
could prevent from releasing memory occupied by all the ScrapeWork items stored in the slice when they
are no longer used.
