Add ProviderUid support to Federated Ingress
This PR (along with GLBC support [here](https://github.com/kubernetes/ingress/pull/278)) is a proposed fix for #39989. The Ingress controller uses a configMap reconciliation process to ensure that all underlying ingresses agree on a unique UID. This works for all of GLBC's resources except firewalls which need their own cluster-unique UID. This PR introduces a ProviderUid which is maintained and synchronized cross-cluster much like the UID. We chose to derive the ProviderUid from the cluster name (via md5 hash).
Testing here is augmented to guarantee that configMaps are adequately propagated prior to Ingress creation.
```release-note
Federated Ingress over GCE no longer requires separate firewall rules to be created for each cluster to circumvent flapping firewall health checks.

gives each ingress object a cluster-unique Uid that can be
leveraged by ingress providers.
In the process, supplement the testing of configMap updates to
ensure that the updates are propagated prior to any ingress
object being created. Configmap key/vals for Uid and ProviderUid
must exist at time of Ingress creation.

Revert conditional updates to configmap that breaks ingress
Don't prevent configmap updates to happen on existing ingress-uid configmap despite the lack of ingress objects. Otherwise, ingress objects get created with the wrong name.

Fix a bug in cascading deletion of federation objects
When FinalizerOrphan is present and set to true in federated object we are currently removing the FinalizerOrphan first and then removing FinalizerDeleteFromUnderlyingClusters. if a reconciliation is triggered in between the finalizer removals, it has undesired effect of object deletion in federated cluster.
So we should remove FinalizerDeleteFromUnderlyingClusters first and then remove FinalizerOrphan, when FinalizerOrphan is set to true.
