  1. Revert "Set temporary single CPU affinity..." 

    There's too much logic here figuring out which CPUs to use. Runc is a
low level tool and is not supposed to be that "smart". What's worse,
this logic is executed on every exec, making it slower. Some of the
logic in (*setnsProcess).start is executed even if no annotation is set,
thus making ALL execs slow.

Also, this should be a property of a process, rather than annotation.

The plan is to rework this.

This reverts commit afc23e3.
