The root span should exist the duration of the trace. Defer ending span
until the end of the trace instead of end of function. Add the span to
the service struct to do so.

AMD SEV pre-attestation is handled by the runtime before the guest is
launched. Guest VM is started paused and the runtime communicates with a
remote keybroker service (e.g., simple-kbs) to validate the attestation
measurement and to receive launch secret. Upon validation, the launch
secret is injected into guest memory and the VM is started.

Some clients like nerdctl may pass mount type of none for volumes/bind mounts,
this will lead to container start fails.
Referring to runc, it overwrites the mount type to bind and ignores the input value.

The tests ensure that interactions between drop-ins and the base
configuration.toml and among drop-ins themselves work as intended,
basically that files are evaluated in the correct order (base file
first, then drop-ins in alphabetical order) and the last one to set
a specific key wins.

updateFromDropIn() uses the infrastructure built by previous commits to
ensure no contents of 'tomlConfig' are lost during decoding. To do
this, we preserve the current contents of our tomlConfig in a clone and
decode a drop-in into the original. At this point, the original
instance is updated but its Agent and/or Hypervisor fields are
potentially damaged.
To merge, we update the clone's Agent/Hypervisor from the original
instance. Now the clone has the desired Agent/Hypervisor and the
original instance has the rest, so to finish, we just need to move the
clone's Agent/Hypervisor to the original.

These functions take a TOML key - an array of individual components,
e.g. ["agent" "kata" "enable_tracing"], as returned by BurntSushi - and
two 'tomlConfig' instances. They copy the value of the struct field
identified by the key from the source instance to the target one if
necessary.
This is only done if the TOML key points to structures stored in
maps by 'tomlConfig', i.e. 'hypervisor' and 'agent'. Nothing needs to
be done in other cases.

For 'tomlConfig' substructures stored in Golang maps - 'hypervisor' and
'agent' - BurntSushi doesn't preserve their previous contents as it does
for substructures stored directly (e.g. 'runtime'). We use reflection
to work around this.
This commit adds three primitive operations to work with struct fields
identified by their `toml:"..."` tags - one to get a field value, one to
set a field value and one to assign a source struct field value to the
corresponding field of a target.

Return code is an int32 type, so if an error occurred, the default value
may be zero, this value will be created as a normal exit code.
Set return code to 255 will let the caller(for example Kubernetes) know
that there are some problems with the pod/container.

Let's add a `default_maxmemory` configuration, which allows the admins
to set the maximum amount of memory to be used by a VM, considering the
initial amount + whatever ends up being hotplugged via the pod limits.
By default this value is 0 (zero), and it means that the whole physical
RAM is the limit.

Now kata shim only supports stdout/stderr of fifo from
containerd/CRI-O, but shim v2 supports logging plugins,
and nerdctl default will use the binary schema for logs.
This commit will add the others type of log plugins:
- file
- binary
In case of binary, kata shim will receive a stdout/stderr like:
binary:///nerdctl?_NERDCTL_INTERNAL_LOGGING=/var/lib/nerdctl/1935db59
That means the nerdctl process will handle the logs(stdout/stderr)

Policy for whats valid/invalid within the config varies by VMM, host,

translating a toml to the hypervisor config structure, and leave
validation to virtcontainers.

Before, we maintained almost identical structures between our persist
API and what we keep for our devices, with the persist API being a
slight subset of device structures.
Let's deduplicate this, now that persist is importing device package.
Json unmarshal of prior persist structure will work fine, since it was
an exact subset of fields.

Rather than have device package depend on persist, let's define the

This'll help avoid unecessary dependencies within our core packages.
