tests/throtl: add a new test 004
tests/throtl: add a new test 005
Do you guys have any suggestions on these tests? Our clients
report a problem that iops limit will cause IO hang, root cause
is the same as [1], and this behaviour is introduced by commit
9f5ede3c01f9 ("block: throttle split bio in case of iops limit"),
splited IO will be re throttled at the tail of bio list.
And we're planing to fix this(Our clients don't accept this behaviour),
by spliting bio-list into a bps throttled list and iops throttled list,
so if iops is within limit, splited IO can be dispatched directly. And
it'll be good to still have a place upstream for functional tests.
