feat: (IAC-1266) (IAC-1186) Update kubectl to 1.27 and add support for ingress-nginx v1.9.X

[riragh]

Changes:

This PR updates the kubectl version to 1.27 and also updates the ingress-nginx version to 1.9.5 which supports the K8 versions: 1.28, 1.27, 1.26, 1.25.

Note: The logic was updated to support the latest version of ingress by default. For any K8s version out of range for the given ingress version would now need to specify INGRESS_NGINX_CHART_VERSION to avoid error.

For example: The latest ingress Helm Chart Version is 4.9.0 which supports K8s range 1.28, 1.27, 1.26, 1.25. For K8s version < 1.25.X, user needs to specify INGRESS_NGINX_CHART_VERSION. Not specifying the INGRESS_NGINX_CHART_VERSION will result in following error:

fatal: [localhost]: FAILED! => {
    "changed": false,
    "msg": "INGRESS_NGINX_CHART_VERSION isn't set when K8s version is < 1.25."
}

Tests:

Verified following scenarios, please details in internal ticket:
