Edge cluster <EDGE_CLUSTER_PATH> cannot be modified when used by interfaces [/infra/tier-0s/<T0_GATEWAY_ID>/locale-services/<LOCALE_SERVICE_ID>/interfaces/<INTERFACE_ID1>, /infra/tier-0s/<T0_GATEWAY_ID>/locale-services/<LOCALE_SERVICE_ID>/interfaces/<INTERFACE_ID1>] and services
NSX-T Data Center 3.1.x
Creating Tier-0 Gateway with invalid edge cluster path is usually rejected.
In 3.1.x, edge cluster path is synchronized every 5 minutes so creating Tier-0 Gateway immediately after deleting Edge Cluster is unexpectedly accepted.
Resolved in NSX Data Center 3.2.x.
