Since the kata's hypervisor process is in the network namespace, which is close to container's process, and some host metrics such as cadvisor can use this pid to access the network namespace to get some network metrics. Thus this commit replace the shim's pid with the hypervisor's pid. Fixes: #1451 Signed-off-by: fupan.lfp <fupan.lfp@antfin.com>
