CA-404297: Should not bring up extra interfaces

XS8 use initscripts to manage interface, thus it
- Write configuration (/etc/sysconfig/network-scripts/ifcfg-xxx)
for all interfaces
- Bring up only the interested interface

In XS9, systemd-networkd is managing the interfaces.
After configuration for all interfaces, `networkctl reload` just
bring up all interfaces. This is not right as extra interfaces
are brought up.

To fix the issue, only the interested interface should be configured
