io.katacontainers.config.runtime.cc_init_data specifies initdata used by
the pod in base64(gzip(initdata toml)) format. The initdata will be
encapsulated into an initdata image and mount it as a raw block device
to the guest.
The initdata image will be aligned with 512 bytes, which is chosen as a
usual sector size supported by different hypervisors like qemu, clh and
dragonball.
Note that this patch only adds support for qemu hypervisor.

Kata-agent now will check if a device /dev/vd* with 'initdata' magic
number exists. If it exists, kata-agent will try to read it. Bytes 9~16
are the length of the compressed initdata toml in little endine.
Bytes starting from 17 is the compressed initdata.
The initdata image device layout looks like
0 8 16 16+length ... EOF
'initdata' length gzip(initdata toml) paddings
The initdata will be parsed and put as aa.toml, cdh.toml and
policy.rego to /run/confidential-containers/initdata.
When AgentPolicy is initialized, the default policy will be overwritten
by that.
When AA is to be launched, if initdata is once processed, the launch arg
will include --initdata parameter.
Also, if
/run/confidential-containers/initdata/aa.toml exists, the launch args
will include -c /run/confidential-containers/initdata/aa.toml.
When CDH is to be launched, if initdata is once processed, the launch
args will include -c /run/confidential-containers/initdata/cdh.toml

When making new tests required, or removing existing tests
from required, this doesn't impact the CI jobs, so we don't need
to run all the tests.

Put local dependencies into workspace to avoid complex path dependencies all
over the workspace. This gives an overview of local dependencies this workspace
uses, where those crates are located, and simplifies the local dependencies
referencing process.

Judging by the layout of the `Cargo.toml` files, local dependencies are
intentionally separated from other dependencies, let's enforce it
workspace-wise.

Just get base name from iommu group symlink is enough. As the
validation will be handled in subsequent steps when constructing
the full path /sys/kernel/iommu_groups/$iommu_group.
In this PR, it will remove dupicalted validation of iommu_group.

For those not interested in CoCo, let's at least allow them to easily
build the agent without the guest-pull feature.
This reduces the binary size (already stripped) from 25M to 18M.

This commit introduces missing validations for input fields in ExecProcessRequest to
harden the security policy.
The changes include:
- Update rules.rego to add null/empty field enforcements for String_user, SelinuxLabel and ApparmorProfile
- Add unit test cases for ExecProcessRequest for each of the validations

While running `cargo fmt -- --check` in `src/runtime-rs` directory, it
