To resolve the issues in tests with disks overload decided initially to implement the disk usage statistics.
Part of tarantool/tarantool-qa#97
Working on this issue and after creating pull request with solution found that the current statistic is really good and fine for HDD based hosts. But for SSD this statistics doesn't show anything countable except that any of SSD parallel RW channels were in use, but not all, while SSD may have it and 16 and 64 and use only some of it doesn't feed and overload its use. We use in Github Actions and in MCS only hosts with SSD which are really fast and such patch won't help us any kind. Decided to stop this work till it will be needed.
