Describe the Feature Request
Add kubelogin to this docker image.

Is your feature request related to a particular problem?
AKS authentication using Azure AD require to have kubelogin installed: https://azure.github.io/kubelogin/index.html

How will this feature request benefit CircleCI jobs using this image?
Reduce execution time and complexity of config.yml file by having kubelogin pre-installed.

Describe the solution you would like to see
I like to see kubelogin installed by default in the image.

Describe alternatives you have considered
In config.yml file, before getting kube config for AKS, I use this script to install kubelogin:

wget https://github.com/Azure/kubelogin/releases/download/"$VERSION"/kubelogin-"$PLATFORM".zip
unzip kubelogin-"$PLATFORM".zip
[ -w /usr/local/bin ] && SUDO="" || SUDO=sudo
$SUDO find bin -name kubelogin -exec mv {} /usr/local/bin/kubelogin \;
kubelogin --version

After getting kube config, I run this script to patch it, enabling using kubelogin:

sed -i -e 's/devicecode/azurecli/g' "$HOME/.kube/config"

An alternative is to add these commands to azure-aks orb.
