resources: disk bound tests need to run in special way

[avtikhon]

During investigation issue #24 found that there was the issue with not enough timeout to finish the test on host with too huge disk bound usage from this test. It produced the discussion how highly disk bound test should be run - this issue created to provide way for such tests. Main disk activities happens on tests with vinyl configuration either 'vinyl/' suite. To investigate this issue more deep investigation is needed:

• need to implement 'vardisk' disk usage collection routine (Collect statistics for 'vardisk' disk usage test-run#308)
• need to create solution to run such tests

1. need to check all tests and find disk bound tests

I would want to collect statistics right from test-run or in some way that works in CI. So we'll see actual behaviour in CI.
