Azat Khuzhin 0e1c6b6b9c Make 01810_max_part_removal_threads_long more accurate 
v0: After parts removing stop attach/detach for each remove, there are only
    11 threads, primary query and 10 for removal.

    CI: https://s3.amazonaws.com/clickhouse-test-reports/34001/8cace291d17fa9553a98b2a1e8bf15b30fe5a1bd/stateless_tests__debug__actions__[3/3].html

v2: Make 01810_max_part_removal_threads_long more deterministic

    Sometimes, if removing parts will be too fast (like in [1]), then it may
    use less threads, since thread pool will reuse existing, so increase
    number of rows per part and compare threads directly w/o throwIf().

      [1]: https://s3.amazonaws.com/clickhouse-test-reports/34001/e74b6379a58c4607bdb54cd4c457410166e869ca/stateless_tests_flaky_check__address__actions_.html

v3: Less flaky 01810_max_part_removal_threads_long
v4: Make check not strict in 01810_max_part_removal_threads_long
