Without explicit image_type fio first sequential write hits
sector 0 and gets VIRTIO_BLK_S_IOERR. fio then hangs, causing
block_write_MiBps and all other write tests using
BLK_IO_TEST_IMG to time out.

Add performance tests for standalone qcow2 images without backing

includes single queue and multiqueue tests for sequential
read, random read and warmed up sequential read.

The backing_files option defaults to false, so qcow2 overlay

Introduce a new BlockControl struct to encapsulate fio operation
parameters. This replaces the tuple-based fio_control with a more
extensible structure that includes:
- fio_ops: The FIO operation type
- bandwidth: Whether to measure bandwidth or IOPS
- test_file: The file path to test against
This refactoring enables reusing performance_block_io with different
test files.

By introducing `imports_granularity="Module"` format strategy,
effectively groups imports from the same module into one line or block,
improving maintainability and readability.
Signed-off-by: Ruoqing He <heruoqing@iscas.ac.cn>
Historically the Cloud Hypervisor coding style has been to ensure that
all imports are ordered and placed in a single group. Unfortunately
cargo fmt has no support for ensuring that all imports are in a single
group so if whitespace lines were added as part of the import statements
then they would only be odered correctly in the group.
By adopting "group_imports="StdExternalCrate" we can enforce a style
where imports are placed in at most three groups for std, external
crates and the crate itself. Choosing a style enforceable by the tooling
reduces the reviewer burden.

Partially revert 111225a2a5
and add the new dbus and pvpanic arguments.
As we are switching back to clap observe the following changes.
A few examples:
1. `-v -v -v` needs to be written as`-vvv`
2. `--disk D1 --disk D2` and others need to be written as `--disk D1 D2`.
3. `--option value` needs to be written as `--option=value.`
Change integration tests to adapt to the breaking changes.

The test virtio_net_latency_us recently failed because of the ethr tool
couldn't complete the latency measurement with the following error
message:
Error dialing the latency connection: dial tcp4
:0-\u003e172.19.0.2:8888: connect: connection refused
The "connection refused" error comes from the Golang Dial function which
couldn't complete as expected because there was no server listening on
the specified port at the specified destination.
In other words, the ethr server wasn't ready when the ethr client tried
to connect to it.
The easy way to avoid this problem is simply by increasing the sleep
time between the command spawning the ethr server in the guest and the
command running the ethr client from the host.
