Azat Khuzhin 9eef2ad0c2 perf: reduce number of times the query will run
Before this patch:

- upstream/master and PR's *with* perf tests or pef scripts changes:
  --runs=13 --max-queries=0

- PRs *without* perf changes:
  --runs=7 --max-queries=20

- PRs w/ only perf tests changes:
  --runs-13 --max-queries=0 <list of perf tests>

After:

- upstream/master and PR's *with* perf tests changes:
  --runs=13 --max-queries=0

- PRs *without* perf changes:
  --runs=7 --max-queries=10

- PRs w/ only perf tests changes:
  --runs-13 --max-queries=0 <list of perf tests>

So to underline, now we will not look at perf scripts changes anymore,
and we will also decrease number of random queries to run to 10.
