    I'd suggest using the following name:
    `--disallow_sharing_agent_pid_namespace`
    
    I would mention in the comment that if set to `true`, and if the framework requests to share the agent pid namespace for the top level container, the conatiner launch will be rejected.

I took a look at other docs (e.g., `mesos-containerizer.md` and `nested-container-and-task-group.md`), they all use `pid namespace`, so I'd like to keep consistent with them.

@Jie and @Gilbert, I know the original proposed flag name is `--disallow_top_level_pid_ns_sharing`, however, I went through all the agent flags, it seems there is no one named with `--disallow` or `--allow` as the prefix, that's why I named it `--share_pid_namespace`. However, I agree the original name is more explicit and clear, so I will change it back later.

@Qian, I guess you are trying to simplify the agent flag name, but I think we may want to emphasize that:
1. this is for top level container only
2. it is operator specific

Do you have anyother concern for the flag name mentioned in the JIRA?

why we need this flag? I think we need a way for operator to prevent top level containers on a host to share with agent pid namespace.
