Description of problem

When integrated kata into other container runtime such as Frakti using its API,
if the sandbox release api is called to disassociate the sandbox, the kataBuiltInProxy will
be closed and will stop the watching of vm's console. Once try to associate with the sandbox by
calling FetchSandbox api, it will lose the vm's console watching.

Expected result

Once the sandbox is fetched and restored, the kataBuiltInProxy will be restarted to
monitor the vm's console.
