lib/promscrape: reduce latency for k8s GetLabels (#2454) 
replaces internStringMap with sync.Map - it greatly reduces lock contention
concurently reload scrape work for api watcher - each object labels added by dedicated CPU

changes can be tested with following script https://gist.github.com/f41gh7/6f8f8d8719786aff1f18a85c23aebf70

lib/promscrape: optimize getScrapeWork() function 
Reduce the number of memory allocations in this function. This improves its performance by up to 50%.
This should improve service discovery speed when big number of potential targets with big number of meta-labels
are generated by service discovery.

* lib/promscrape: adds job restart method
it must restart only ScrapeConfig with changed content
this change greatly reduce time, that needed for job restart
and it should decrease possible data loss when config frequently changed at kubernetes based deployments

71ea4935de lib/promscrape: add -promscrape.suppressDuplicateScrapeTargetErrors command-line flag in order to suppress duplicate scrape target errors 
Show also original labels for duplicate targets in error message in order to simplify debugging the issue.

Now `/targets` endpoint accepts optional `show_original_labels=1` query arg, which shows original labels for each target.
This may simplify debugging for target relabeling.
