[feature request] add IsCRIEnabled field in `/info` API and show it in `pouch info` cli

[allencloud]

Ⅰ. Issue Description

Currently PouchContainer has supported enabling CRI part to be called by kubelet. Then when deploying PouchContainer in Kubernetes, we need to provide a user-friendly way tell deployer whether pouchd has enabled CRI or not?

So, I request a feature that a field IsCRIEnabled bool could be covered in api/types/system_info.go.

Then, when executing pouch info, there is a line of IsCRIEnabled: true or IsCRIEnabled: false.

Ⅱ. Describe what happened

no cri enabled information is covered in pouch info

Ⅲ. Describe what you expected to happen

when executing pouch info, there is a line of IsCRIEnabled: true or IsCRIEnabled: false.

Ⅳ. How to reproduce it (as minimally and precisely as possible)

Ⅴ. Anything else we need to know?

Ⅵ. Environment:

• pouch version (use pouch version):
• OS (e.g. from /etc/os-release):
• Kernel (e.g. uname -a):
• Install tools:
• Others:
