This test:
- starts up 2 minikube clusters
- create 2 ceph clusters
- creates object multisite CRDs on each cluster and
syncs the clusters
- writes an object to cluster 1 and reads it on
cluster 2
This commit also adds new functions in
github-action-helper.sh that aid in the multisite
test and the multi cluster mirroring test.
