- Replaces use of manual `zpool sync` - Don't use `log_must sync_pool` as `sync_pool` uses it internally - Replace many (but not all) uses of `sync` with `sync_pool` This makes the tests more consistent, and makes searching easier.

# DESCRIPTION:
|
|
# Verify scrub behaves as intended when contending with a healing or
|
|
# sequential resilver.
|
|
#
|
|
# STRATEGY:
|
|
# 1. Create a pool
|
|
# 2. Add a modest amount of data to the pool.
|
|
# 3. For healing and sequential resilver:
|
|
# a. Start scrubbing.
|
|
# b. Verify a resilver can be started and it cancels the scrub.
|
|
# c. Verify a scrub cannot be started when resilvering
|
|
