[PATCH 4/4] t/zbd: Add support to verify Zone Append command with libaio, io_uring IO engine tests

[Krishna Kanth Reddy <krish.reddy@xxxxxxxxxxx>]

Modify the test-zbd-support script to verify the Zone Append command
for NVMe Zoned Namespaces (ZNS) defined in NVM Express TP4053.
Added a new FIO option zone_append.
When zone_append option is enabled, the existing write path will
send Zone Append command with LBA offset as start of the Zone.
