ZTS: Test case reliability

Browse Source 
* Both cli_root/zpool_import/import_cache_device_replaced, and
  redundancy/redundancy_004_neg have been observed to fail for
  spurious reasons ~1% of the time.  Add them to the exception
  list and reference the open Github issue.

* Speed up replacement/replacement_001_pos to prevent it from
  exceeding the 10 minute per test limit and getting KILLED.
  File vdev creation switched to truncate -s, redundant raidz1
  testing pass dropped, fixed some minor formating issues.
