* CKS: retry if unable to drain node or unable to upgrade k8s node
I tried CKS upgrade 16 times, 11 of 16 upgrades succeeded.
2 of 16 upgrades failed due to
```

* CKS: remove tests of creating/deleting HA clusters as they are covered by the upgrade test
* Update PR 8402 as suggested
* test: remove CKS cluster if fail to create or verify
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.

api: fix new password is applied on host when update host password with update_passwd_on_host=false (#7092)
CKS: remove details when delete a cks cluster (#7104)
api/server: add project id/name in ssh keypair response (#7100)
* Export count of total/up/down hosts by tags
* Export count of vms by state and host tag.
* Add host tags to host cpu/cores/memory usage in Prometheus exporter
* Cloudstack Prometheus exporter: Add allocated capacity group by host tag.
* Show count of Active domains on grafana.
* Show count of Active accounts and vms by size on grafana
* Use prepared statement to query database for a number of VM who use a specific tag.
* Extract repeated codes to new methods.
Adds option to provide custom DNS servers for isolated network, shared network and VPC tier.
New API parameters added in createNetwork API along with the corresponding response parameters.

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.
From /etc/login.defs:
ENV_SUPATH PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
ENV_PATH PATH=/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games
