Add "Deploy Azure" stage

This stage contains jobs to deploy packaged artifacts to our Azure blob storage. The required variables AZURE_STORAGE_ACCOUNT and AZURE_STORAGE_SAS_TOKEN are stored in the GitLab CI/CD variables. The storage container AZURE_CONTAINER_NAME and artifact path AZURE_TARGET_FOLDER are passed from the parent pipeline.
