To support recovery of network failures during rename, the abfs client fetches the etag of the source file, and when recovering from a failure, uses this tag to determine whether the rename succeeded before the failure happened. * This works for files, but not directories * It adds the overhead of a HEAD request before each rename. * The option can be disabled by setting "fs.azure.enable.rename.resilience" to false Contributed by Sree Bhattacharyya
