Subject: [PATCH] gh/workflow: change multicluster provisioning to none
 blocking mode

Multicluster test set up two clusters in blocking mode in sequentially.
Every cluster provisioning takes 4 to 5 min.
This commit changes provisioning to none blocking mode and adds
a step to wait for provisioning to finish.

This change would cut the run time by 4 to 5 min.
