David Calavera f1a74a89f8 Use an empty slice as default value for DNS, DNSSearch and DNSOptions
So we don't print those <no value> in the client and we don't fail
executing inspect templates with API field names.

Make sure those fields are initialized as empty slices when
a container is loaded from disk and their values are nil.
