deploy/cobbler: drop tcp_tw_recycle in sysctl.conf
Currently, tcp_tw_recycle is set explicitly in sysctl.conf when
installing OS by cobbler. This option is removed in kernel4.12,
current sysctl.conf breaks sysctl function and K8s deployment.
Actually, tcp_tw_recycle is considered broken and not recommended to
use. We may simply drop this option to be compatible with different
kernel versions.
