Calico Kubernetes Certificate Error during Master Node setup

[aryans1204]

Describe the bug
After step 3.2 from the Quickstart guide, and joining the Kubernetes cluster on the worker nodes, the master node setup provides an error with validation error of the Kubernetes issued certificate while setting up Calico. This fails the master node setup process.

To Reproduce
On a 2 machine cluster, follow steps from quickstart guide until 3.2.
Execute ./setup_tool create_multinode_cluster firecracker on the master node and click y after executing sudo kubeadm join IP:PORT --token <Token> --discovery-token-ca-cert-hash <Token Hash> > >(tee -a /tmp/vhive-logs/kubeadm_join.stdout) 2> >(tee -a /tmp/vhive-logs/kubeadm_join.stderr >&2) on the worker node. Upon the worker node successfuly joining the cluster, the error is thrown on the master node, killing the cluster setup process.

Expected behavior
Successfully applied Calico.
Successfully started multinode cluster.

Please add relevant excerpts from the following logs: vhive, firecracker-containerd,
and if used with Kubernetes additionally containerd and/or other relevant
logs of Kubernetes containers and setup scripts.

Notes
Currently, we support only Ubuntu 18 (x86) bare-metal hosts, however
we encourage the users to reports Issues that appear in different settings.
We will try to help and potentially include these scenarios into our CI
if given enough interest from the community.

Please terminate and re-deploy the cluster, and then try again.
