Title:
  Setting "enable_quotas"=False disables Neutron in  GUI

Status in OpenStack Dashboard (Horizon):
  Fix Released
Status in OpenStack Dashboard (Horizon) kilo series:
  Fix Released

Bug description:
  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. KeyError Exceptions are 
  thrown.

  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.
