CentOS 7 integrated gate optimization

The CentOS 7 AIO jobs time out fairly frequently in the gates and
this patch switches the jobs to use the new aio_basekit scenario in
the hopes that jobs will complete more often.

This patch also sets SELinux to Permissive mode for CentOS 7 gate
testing. This can be changed back to Enforcing when CentOS 7's
SELinux policies are ready.

This patch also sets package_state to present for CentOS 7 jobs. This
is a temporary measure to ensure more of the gate jobs can finish on
time and we can expose deployment issues in the gates.
