t/zbd: Add test #58 to test zone reset by trim workload

To exercise zone reset by trim workload, add the test case #58. As the
precondition, it fills several zones. After that, a trim job and a write
job run in parallel for 30 seconds. The ratio of trim commands and write
commands is controlled by --flow option.
