You need to use metric_relabel_configs, not relabel_configs.
* relabel_configs is run for the target relabelling phase, *before* scraping.
It can be used to modify the address and port being scraped.
* metric_relabel_configs is run *after* scraping. It can be used to modify
or drop the metrics returned by the scrape.
Also, I believe the label names are case-sensitive.
