DESCRIPTION:
    This sample demonstrates listing all the metric namespaces of a resource.
USAGE:
    python sample_metric_namespaces.py
    Set the environment variables with your own values before running the sample:
    1) METRICS_RESOURCE_URI - The resource URI of the resource for which the metrics are being queried.

    This example uses DefaultAzureCredential, which requests a token from Azure Active Directory.
    For more information on DefaultAzureCredential, see https://learn.microsoft.com/python/api/overview/azure/identity-readme?view=azure-python#defaultazurecredential.

    In this example, a Storage account resource URI is taken.
