Merge pull request #12933 from prymitive/duplicated_samples ...

When Prometheus scrapes a target and it sees the same time series repeated multiple times it currently silently ignores that. This change adds a test for that and fixes the scrape loop so that:

* Only first sample for each unique time series is appended
* Duplicated samples increment the prometheus_target_scrapes_sample_duplicate_timestamp_total metric
This allows one to identify such scrape jobs and targets.

Also fix some tests and benchmark.
