Public bug reported:

Excluding OPENSTACK_NEUTRON_NETWORK["enable_quotas"] or setting to False
will result in Create Network, Create Subnet, Create Router buttons
not showing up when logged in as the demo account.  

These three side effects happen because the code in the views use the
following construct
https://github.com/openstack/horizon/blob/master/openstack_dashboard/dashboards/project/networks/tables.py#L94

        usages = quotas.tenant_quota_usages(request)
        if usages['networks']['available'] <= 0:

if enable_quotas is false, then quotas.tenant_quota_usages does not add
the 'available' node to the usages dict and therefore a KeyError
'available' is thrown. This ends up aborting the whole is_allowed method
in horizon.BaseTable and therefore hiding the button.

quotas.tenant_quota_usages will not add the available key for usage
items which are disabled.
