With the update of openstack clients:
openstack client >= 4.0.0
neutron client >= 6.14.0
neturon lib >= 1.29.1
The command 'openstack network show ${network} -f value -c subnets'
returns '[]' instead of null string if no subnets found in the
specific network. This commit adds a check logic to avoid subsequent
command returns error by using '[]' as subnet input.
