Add support for using zone append commands instead of write command,
for bdevs that support it.
In the SPDK NVMe plugin, the target struct (called spdk_fio_qpair) is
allocated in .setup(), but the qpair is first created in .open_file.
In the SPDK bdev plugin, the target struct (called spdk_fio_target)
is allocated in spdk_fio_bdev_open(). This function also creates the
I/O channel. (spdk_fio_bdev_open() is called by .init().)
Since certain options has to be saved in the struct spdk_fio_target,
which is allocated quite late, we cannot reuse spdk_fio_handle_options(),
which has to be called before threads are created.
Therefore, we unfortunately need another option parsing function in the
SPDK bdev plugin.
If we fail to handle any of the per target options, the target is never
added to the list of targets, and is freed immediately.
