Subject: [PATCH] feat: Allow ACR authentication using Azure CLI

Install azure-cli in Docker image in order to use the `az acr login` command.

Can be used with Azure Managed Identities with the following script:

```yaml
---
apiVersion: v1
kind: ConfigMap
metadata:
  name: argocd-image-updater-config
  namespace: argocd
data:
  log.level: debug
  registries.conf: |
    registries:
    - name: acrexample
      api_url: https://acrexample.azurecr.io/
      prefix: acrexample.azurecr.io
      ping: yes
      insecure: no
      credentials: ext:/app/scripts/acr-login.sh
      credsexpire: 10h
---
apiVersion: v1
kind: ConfigMap
metadata:
  name: argocd-image-updater-config-acr
  namespace: argocd
data:
  acr-login.sh: |
    #!/bin/sh
    LOGIN=$(az login --identity)
    REGISTRY="acrexample"
    TOKEN=$(az acr login --name $REGISTRY --expose-token --output tsv --query accessToken)
    echo "00000000-0000-0000-0000-000000000000:$TOKEN"
```

Closes #550 and #473
