This looks like it was copy and pasted from the network test which
required 2 vCPUs per queue pair but has since been resolved.

Using the default queue sizes provides more realistic data about what
our users are testing. Extra metrics can be added later that also
modify the queue size but overloading the existing metrics is confusing.

Don't treat it as the number of pairs. Instead calculate the number of
pairs later when necessary.

Also be clear that the block tests are in bytes per second (Bps) vs
network that is in bits per second (bps).

The former is ambiguous as it could be considered the ordinal (and is
used elsewhere in the codebase for that).

Many of the tests already amortize their results over a longer time
period/sample so it is not necessary to run 30 iterations.

Let's officially have a way to pass the features used to build
cloud-hypervisor to the dev_cli.sh script.
This doesn't invalidate the previous commit, as we still don't what the
features_build variable to be quoted, otherwise we face the following
issue:
```
error: Found argument '--features tdx' which wasn't expected, or isn't valid in this context
Did you mean --features?
USAGE:
cargo build --all --features <FEATURES>...
```

2805e7b1dc quoted enclose variables to
prevent globbing or incorrect splitting. However, by doing with with
$features_build it broke the capability to call the script as:
```
$ ./scripts/dev_cli.sh build --release --libc musl -- --features tdx
```
Before 2805e7b1dc it simply worked, after,
the result is:
```
docker run --user 1000:1000 --workdir /cloud-hypervisor --rm --volume /dev/kvm --volume /home/ffidenci/go/src/github.com/cloud-hypervisor/cloud-hypervisor:/cloud-hypervisor --env RUSTFLAGS= cloudhypervisor/dev:20220223-0 cargo build --all '' --target-dir /cloud-hypervisor/build/cargo_target --features tdx --release --target x86_64-unknown-linux-musl
error: Found argument '' which wasn't expected, or isn't valid in this context
USAGE:
cargo build --all

For now only generate the boot time related tests as the full metrics
test suite needs some more time to bed in.

The dev container interface script (e.g. 'dev_cli.sh') now supports the
following arguments syntax for running tests:
`tests [--unit|--cargo|--all] [--libc musl|gnu] [-- [<test scripts args>] [-- [<test binary args>]]] `
In this way, we can pass custom arguments to the test binary (either
"cargo test" or "performance-metrics") with our dev container script.
For example:
`$ ./dev_cli.sh tests --metrics -- -- --report-file /tmp/metrics.json --test-filter latency`
`$ ./dev_cli.sh tests --integration -- --test-filter "test_serial" -- --nocapture --test-threads=1`

We don't need to install docker inside the container. Add missing

The same way we mask the writes coming from the guest to the message
control register related to MSI-X capability, let's do the same for MSI.
The point is to prevent the guest from writing to read-only bits.
The correct writable bits for MSI are only bits 0, 4, 5 and 6 of 2nd
16-bit word.
Those are:
* MSI Enable: 0
* Multiple Message Enable: 6-4
See "Table 7-39 Message Control Register for MSI" from
"NCB-PCI_Express_Base_5.0r1.0-2019-05-22.pdf".

Starting from Rust 1.56 Cargo supports specifying the minimum supported
rust version (MSRV) via "rust-version". If the compiler version is not
satisfied, Cargo prints an error and exits early.
MSRV is useful information to packagers. Using this field also saves us
from adding another file to the tree.
The version is currently set to 1.54, which is tested to build Cloud
Hypervisor successfully. Although anyone who uses 1.54 will see a
warning because "rust-version" is only introduced in 1.56. The warning
can be safely ignored.
