  1. config: add annotation for exec isolated CPU affinity 

    The runc container runtime recently introduced functionality to direct exec
operations to the first isolated CPU in a container cgroup cpuset. This is
enabled through a new runc specific container annotation:
org.opencontainers.runc.exec.isolated-cpu-affinity-transition

See opencontainers/runc@afc23e3397 for the details.

This new functionality is also required in the crun container runtime and will
be added soon. This purpose of this commit is to add a new annotation to the
OCI runtime specification that would be used by any runtime that implements
this new functionality:
org.opencontainers.runtime.exec.isolated-cpu-affinity-transition

The runc implementation should switch to using the new annotation once it is
accepted.
