feature.

Now that we only use hypervisor config to set them, they
are not overridden by other configs. So drop the default prefix.

The CLI being the implementation of the OCI specification, and the
hooks being OCI specific, it makes sense to move the handling of any
OCI hooks to the CLI level. This changes allows the Kata API to
become OCI agnostic.

This commit moves the network namespace creation out of virtcontainers
in order to anticipate the move of the OCI hooks to the CLI through a

Since we removed the CNI implementation and that we agreed the network
should only be handled in a single way from virtcontainers, this patch
logically replace the "CNM" naming with "Default".

Add additional `context.Context` parameters and `struct` fields to allow
trace spans to be created by the `virtcontainers` internal functions,
objects and sub-packages.
Note that not every function is traced; we can add more traces as
desired.

We dont really call CNI from Kata, this is done by the CRI layer.

When enabled, do not release in memory sandbox resources in VC APIs,
and callers are expected to call sandbox.Release() to release the in
memory resources.
Signed-off-by: Peng Tao <bergwolf@gmail.com>
For each time a sandbox structure is created, we ensure s.Release()
is called. Then we can keep the qmp connection as long as Sandbox
pointer is alive.
All VC interfaces are still stateless as s.Release() is called before
each API returns.
OTOH, for VCSandbox APIs, FetchSandbox() must be paired with s.Release,
the same as before.

Update command is used to update container's resources at run time.
All constraints are applied inside the VM to each container cgroup.
By now only CPU constraints are fully supported, vCPU are hot added
or removed depending of the new constraint.

Currently we sometimes pass it as a pointer and other times not. As
a result, the view of sandbox across virtcontainers may not be the same
and it costs extra memory copy each time we pass it by value. Fix it
by ensuring sandbox is always passed by pointers.

It disconnects the agent connection and removes the sandbox
from global sandbox list.
A new option `LongLiveConn` is also added to kata
agent's configuration. When set, the API caller is expected
to call sandbox.Release() to drop the agent connection explicitly.
`proxyBuiltIn` is moved out of agent state because we can always
retrieve it from sandbox config instead.

As agreed in [the kata containers API
design](https://github.com/kata-containers/documentation/blob/master/design/kata-api-design.md),
we need to rename pod notion to sandbox. The patch is a bit big but the
actual change is done through the script:
```
sed -i -e 's/pod/sandbox/g' -e 's/Pod/Sandbox/g' -e 's/POD/SB/g'
```
The only expections are `pod_sandbox` and `pod_container` annotations,
since we already pushed them to cri shims, we have to use them unchanged.

It modifies the default QEMU_CMD to be qemu-system-x86_64
