This PR fixes the test failures with CKS HA-cluster upgrade.
In production, the CKS HA cluster should have at least 3 control VMs as well.
The etcd cluster requires 3 members to achieve reliable HA. The etcd daemon in control VMs uses RAFT protocol to determine the roles of nodes. During upgrade of CKS with HA, the etcd become unreliable if there are only 2 control VMs.
There are tools like cluster-api which create and manage kubernetes cluster on CloudStack. This PR adds the option to add unmanaged kubernetes cluster which are not managed by CKS plugin. This helps provide a consolidated view of unmanaged clusters on CloudStack. The changes done make sure that operations for managed clusters are not executed for unmanaged clusters.
Two new APIs have also been added:
1. addVirtualMachinesToKubernetesCluster - to add VMs to unmanaged clusters.
2. removeVirtualMachinesFromKubernetesCluster - to remove VMs to unmanaged clusters.
Two APIs have been updated:
1. createKubernetesCluster - made KUBERNETES_VERSION_ID, SERVICE_OFFERING_ID, SIZE as not required for unmanaged clusters. Add an additional parameter, managed, which is true by default.
2. listKubernetesClusters - Add a parameter managed to filter on managed field.

This change will allow CKS to be enabled by default on new installs. It would not affect server or performance but would help highlighting k8s support in CloudStack.

Fixes#6657
Fixes k8s cluster node VM deployment when the underlying hypervisor host has multiple host tags and the service offering used for the cluster deployment does not contain all of those host tags.
Fixes#6514
On latest systemvm template used for CKS /usr/sbin is not present in the $PATH for normal user used during upgrade. This leads to failure for blkid command. Due to this during k8s version upgrade ISO is not being able to mount on the k8s cluster VMs and upgrade process is not carried out.
This PR fixes mounting of k8s version ISO and also returns failure for script when ISO mounting is failed.
Same failure is not seen during deployment of the cluster because setup-kube-system workflow is executed as ROOT user and it has a different value for $PATH.
