M #-: Skip null values from Equinix response (#1348)

It can happen that Equinix API responses contain null values for certain
attributes (e.g. "facility":null). This fix avoids the provision crashes
with this error "[one.vn.allocate] undefined method `each_pair' for
nil:NilClass" when creating the packet-cluster-public network.
