[MANOPD-90205] fix for vulnerability scanning failure

[pranavcracker]

Description

• When we run the kube-bench on cluster running with k8s v1.27.1 installed using kubemarine 0.18.2, we got below failures-

[FAIL] 1.1.12 Ensure that the etcd data directory ownership is set to etcd:etcd (Automated)

Fixes # (issue)
MANOPD-90205

Solution

• Fix for 1.1.12 - Set to ownership for data directory(/var/lib/etcd) as etcd:etcd

Test Cases

TestCase 1

• Find the latest version of kube-becnh utility https://github.com/aquasecurity/kube-bench/releases

• Upload archive to the master/worker node, for example
  scp -i ~/.ssh/shift_test_key ~/kube-bench_0.6.15_linux_amd64.tar.gz ubuntu@:/home/ubuntu

• Unpack it to the separate folder
  tar -xvf kube-bench_0.6.15_linux_amd64.tar.gz

• Run check as (latest Kubernetes Benchmark will be used by default [https://github.com/aquasecurity/kube-bench/blob/main/docs/platforms.md#cis-kubernetes-benchmark-support])
  ./kube-bench --config-dir <pwd>/cfg --config <pwd>/cfg/config.yaml

Results:

Before	After
[FAIL] 1.1.12 Ensure that the etcd data directory ownership is set to etcd:etcd (Automated)	[PASS] 1.1.12 Ensure that the etcd data directory ownership is set to etcd:etcd (Automated)

As with current solution, we are running the etcd containers with root user and hence we will consider this as known issue with our solution.
Closing this PR as no further action is required.
