* lib/promscrape: support prometheus-like duration in scrape configs The change allows to specify duration values like `1d`, `1w` for fields `scrape_interval`, `scrape_timeout`, etc. https://github.com/VictoriaMetrics/VictoriaMetrics/issues/817#issuecomment-1033384766 Signed-off-by: hagen1778 <roman@victoriametrics.com> * lib/blockcache: make linter happy Signed-off-by: hagen1778 <roman@victoriametrics.com> * lib/promscrape: support prometheus-like duration in scrape configs * add support for extra fields `scrape_align_interval` and `scrape_offset`; * support Prometheus duration parsing for `__scrape_interval__` and `__scrape_duration__` labels; Signed-off-by: hagen1778 <roman@victoriametrics.com> * wip * wip * docs/CHANGELOG.md: document the feature Co-authored-by: Aliaksandr Valialkin <valyala@victoriametrics.com>
