Clusters with disabled resource settings stuck in the `deploying` state

[moklidia]

Some accounts have empty resource quota settings and it used to create unlimited uclusters.
However such clusters now get stuck in the deploying state.

The request sent to the controller:

Decoded HTTP Request: {Name:underneath Manifest: BaseIngressHost:c169597780649203.uclusters.app.qa-gke.uffizzi.com ResourceSettings:{ResourceQuota:{Enabled:false Requests:{CPU: Memory: EphemeralStorage: Storage:} Limits:{CPU: Memory: EphemeralStorage:} Services:{NodePorts:0 LoadBalancers:0} Count:{Pods:0 Services:0 ConfigMaps:0 Secrets:0 PersistentVolumeClaims:0 Endpoints:0}} LimitRange:{Enabled:false Default:{CPU: Memory: EphemeralStorage:} DefaultRequest:{CPU: Memory: EphemeralStorage:}}} SleepAfter:}

The resulting cluster spec:

    apiServer: {}
