BUG/MEDIUM: cli/shutdown sessions: make it thread-safe

There's no locking around the lookup of a stream nor its shutdown
when issuing "shutdown sessions" over the CLI so the risk of crashing
the process is particularly high.

Let's use a thread_isolate() there which is suitable for this task, and
there are not that many alternatives.

This must be backported to 1.8.
