Add a new "use_arrow_list" advanced option which fetches directory listings
using the ListBlobs Apache Arrow response format instead of XML. This can be
substantially faster for very large containers.
This is EXPERIMENTAL and requires the "Blob Listing with Apache Arrow" preview
feature to be enabled on the storage account. It is not supported on accounts
with a hierarchical namespace (ADLS Gen2). If the feature is not enabled the
service returns XML and the listing transparently falls back to it. Connection
string auth is not supported - it also falls back to the normal XML listing.
The option is hidden from the configurator, command line help and docs until the
feature is officially released.
