letting individual policies set their own definition of what that is.
By default, this will attempt to assign sos to an idle io class via
ionice if available. We will also renice our own pid to 19 in order to
not cause competition with other host processes for CPU time.

This will use the container runtime defined for the host type to
launch a container. From there, we use the defined runtime to exec into
the container's namespace.

This is called immediately after create_sos_container() as the command
to create the container will exit and the container will stop. For
current container runtimes, subsequently starting the container will
default to opening a bash shell in the container to keep it running,
thus allowing us to exec into it again.
