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. Fixes: #199 Signed-off-by: Peng Tao <bergwolf@gmail.com>
