The test creates a patch orchestration strategy or plan for automated patching operation with the following

--controller-apply-type : specifies how controllers are patched serially or in parallel. By default controllers are
patched always in serial regardless of the selection.
--storage-apply-type : specifies how the storages are patched. Possible values are: serial, parallel or ignore. The
default value is serial.
--compute-apply-type : specifies how the computes are patched. Possible values are: serial, parallel or ignore. The
default value is serial.
--max-parallel-compute-hosts: specifies the maximum number of computes to patch in parallel. Possible values
[2 - 100]The default is 2.
--instance-action - For reboot-required patches, specifies how the VM instances are moved from compute hosts being
patched. Possible choices are:
start-stop - VMs are stopped before compute host is patched.
migrate - VMs are either live migrated or cold migrated off the compute before applying the patches.
