[Feature Request] Falcon Image Analyzer - Add support of Azure Workload Identity

[YvesEarnix]

Falcon FalconImageAnalyzer not supported Azure Workload Identity ?

Operator CRD documentation mention only "AWS & GCP".

              serviceAccount:
                    description: Define annotations that will be passed down to
                      Image Analyzer service account. This is useful for passing
                      along AWS IAM Role or GCP Workload Identity.

Secondly, crd not allow to patch pod labels required by Azure Workload identity => "azure.workload.identity/use: 'true'"

I patch it manually, but seem not supported as I still face to this error =>

unable to retrieve auth token: invalid username/password: unauthorized: authentication required, visit https://aka.ms/acr/authorization for more information

Although all expected variables was correctly injected on the image analyser pod by the azure workload identity=>

AZURE_TENANT_ID=<....>
AZURE_FEDERATED_TOKEN_FILE=/var/run/secrets/azure/tokens/azure-identity-token
AZURE_AUTHORITY_HOST=https://login.microsoftonline.com/
AZURE_CLIENT_ID=<....>
