To use Microsoft Azure Storage as a board, you'll need an Azure Storage
account, an Azure Storage container, and an Azure Storage key.
You can sign-up and create those at portal.azure.com.
The access key for the Azure Storage container. You can find
this under "Access keys" in your storage account settings.
The key is equivalent to a password, so generally should not be stored
in your script. The easiest alternative is to store it in the
AZURE_STORAGE_KEY environment variable, which legacy_azure() will
use by default.
cache
Cache path. Every board requires a local cache to avoid
downloading files multiple times. The default stores in a standard
cache location for your operating system, but you can override if needed.
name
An optional name used identify the board. This is no longer
generally needed since you should be passing around an explicit
board object.
