Then we can check hypervisor liveness in those cases to avoid long
timeout when connecting to the agent when hypervisor is dead.
For kata-agent, we still use the kata-proxy pid for the same purpose.

kata builtin proxy has always watched the qemu's console
whether proxy's debug is set or not, this is not aligned
with kata cli. This patch will change it and watch the
qemu's console only when proxy's debug is set in kata config.

Callers can use setProxy to ask agent to use an existing proxy.
agent is modified to rely on its state.URL to tell if an
its proxy is a valid one. And startProxy will skip a valid
proxy since it is already started.

A proxy is mostly associated with an agent. Decouple it from sandbox
so that we can start it before linking vm with an actual sandbox.

When do sandbox release, the kataBuiltInProxy will
be closed, and it will stop the watch of vm's console;
Thus it needs to restart the proxy to monitor the vm
console once to restore the sandbox.

A Unix domain socket is limited to 107 usable bytes on Linux. However,
not all code creating socket paths was checking for this limits.
Created a new `utils.BuildSocketPath()` function (with tests) to
encapsulate the logic and updated all code creating sockets to use it.
Fixes#268.

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.

When imported, the vc files carried in the 'full style' apache
license text, but the standard for kata is to use SPDX style.
Update the relevant files to SPDX.

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.

When specified, it does not spawn a new process to proxy kata grpc
connections. Instead, the yamux multiplexing functionality is builtin
in the kata agent dialer.
