    Description copied from interface: BlobStore
    
    Creates a namespace for your blobs
    A container is a namespace for your objects. Depending on the service, the scope can be global, identity, or sub-identity scoped. For example, in Amazon S3, containers are called buckets, and they must be uniquely named such that no-one else in the world conflicts. In other blobstores, the naming convention of the container is less strict. All blobstores allow you to list your containers and also the contents within them. These contents can either be blobs, folders, or virtual paths.
    
    Specified by:
    
    createContainerInLocation in interface BlobStore
    
    Parameters:
    location - some blobstores allow you to specify a location, such as US-EAST, for where this container will exist. null will choose a default location
    name - namespace. Typically constrained to lowercase alpha-numeric and hyphens.
    
    Returns:
    true if the container was created, false if it already existed.
