* vmselect/promql: enable search.maxPointsPerTimeSeriesSubquery for sub-queries * vmselect/promql: cleanup * vmselect/promql: rename config flag * vmselect/promql: add tests * vmselect/promql: use test object instead of log * vmselect/promql: fix posible panic is subquery has more points. add description * vmselect/promql: update tests descriptions * vmselect/promql: update doInternal validation * vmselect/promql: fix linter * vmselect/promql: fix linter * vmselect/promql: update documentation and release notes * wip - Properly apply -search.maxPointsSubqueryPerTimeseries limit to subqueries. Previously the -search.maxPointsPerTimeseries limit was unexpectedly applied to subqueries if it was smaller than the -search.maxPointsSubqueryPerTimeseries . - Clarify docs for -search.maxPointsSubqueryPerTimeseries command-line flag . - Document -search.maxPointsPerTimeseries and -search.maxPointsSubqueryPerTimeseries flags at https://docs.victoriametrics.com/#resource-usage-limits . - Update docs/CHANGELOG.md .
