Subject: [PATCH] LU-6385 tests: Sync OSTs between tests in obdfilter-survey
osd-ldiskfs and osd-zfs operate differently with regards to writeback
cache. This adds a force sync between test runs so that a test list
of "write read" will have all writes finished before reads starts for
both ldiskfs and zfs.
