Allow 'zpool events' filtering by pool name
Additionally add four new tests: * zpool_events_clear: verify 'zpool events -c' functionality * zpool_events_cliargs: verify command line options and arguments * zpool_events_follow: verify 'zpool events -f' * zpool_events_poolname: verify events filtering by pool name Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Reviewed-by: Giuseppe Di Natale <dinatale2@llnl.gov> Signed-off-by: loli10K <ezomori.nozomu@gmail.com> Closes #3285 Closes #6762

# DESCRIPTION:
|
||||
# 'zpool events poolname' should only display events from the chosen pool.
|
||||
#
|
||||
# STRATEGY:
|
||||
# 1. Create an additional pool
|
||||
# 2. Clear all ZFS events
|
||||
# 3. Generate some ZFS events on both pools
|
||||
# 4. Verify 'zpool events poolname' successfully display events
