lib/promscrape: apply sample_limit after metric relabeling is applied as Prometheus does
...
See the description for `sample_limit` option from Prometheus docs:
Per-scrape limit on number of scraped samples that will be accepted.
If more than this number of samples are present after metric relabeling
the entire scrape will be treated as failed. 0 means no limit.

lib/promscrape: rename 'scrape_config->scrape_limit' to 'scrape_config->sample_limit'
...
`scrape_config` block from Prometheus config contains `sample_limit` field,
while in `vmagent` this field was mistakenly named as `scrape_limit`.
