Horizon Network Topology view fails on fresh environment Fuel 8.0

[Sam Stoelinga]

Steps to reproduce:
1. Deploy a new environment with HA + no Ceph consisting only of 1 controller + 1 compute
2. Open Network Topology in horizon

Current result:
Unable to open page it throws an exception. See error below

This is most likely a bug in Horizon.

Fix update of disabled Nova quotas

Since the introduction of disabling Nova quotas in Horizon config (so
they would mirror disabled quotas on Nova side), it became possible
that a specific quota dictionary key (say 'instances') doesn't have a
'quota' key in a corresponding dictionary value (since this exact
quota is disabled). Fix that by treating the absence of 'quota' key as
an infinite quota.

This fix is already included in an upstream patch at
https://review.openstack.org/#/c/215277
