<p>Azure Blob Storage backed FileSystem implementation</p>
<p>This implementation supports flat namespace and hierarchical namespace (HNS) a.k.a.
Data Lake Gen2 storage accounts. HNS will be automatically detected and HNS specific
features will be used when they provide a performance advantage. Azurite emulator is
also supported. Note: <cite>/</cite> is the only supported delimiter.</p>
<p>The storage account is considered the root of the filesystem. When enabled, containers
will be created or deleted during relevant directory operations. Obviously, this also
requires authentication with the additional permissions.</p>
<p>By default <a class="reference external" href="https://github.com/Azure/azure-sdk-for-cpp/blob/main/sdk/identity/azure-identity/README.md#defaultazurecredential">DefaultAzureCredential</a>
is used for authentication. This means it will try several types of authentication
and go with the first one that works. If any authentication parameters are provided when
initialising the FileSystem, they will be used instead of the default credential.</p>
