Azure Container Registry SDK for Python

预期结果:

```python
from azure.containerregistry import ContainerRegistryClient
from azure.identity import DefaultAzureCredential

client = ContainerRegistryClient(
endpoint="https://myregistry.azurecr.io",
credential=DefaultAzureCredential()
)

for repository in client.list_repository_names():
print(repository)
```

预期结果:

```python
from datetime import datetime, timedelta, timezone

cutoff = datetime.now(timezone.utc) - timedelta(days=30)

for manifest in client.list_manifest_properties("my-image"):
if manifest.last_updated_on < cutoff and not manifest.tags:
print(f"Deleting {manifest.digest}")
client.delete_manifest("my-image", manifest.digest)
```
