Use bulk deletes where possible

[cmackenzie1]

Description

Underlying object_store crate has a delete_stream method which if more performant / efficient than calling delete for many files. Where possible, prefer usage of this function.

For example:

delta-rs/rust/src/protocol/checkpoints.rs

Lines 154 to 162 in a67140c

	let deleted = files_to_delete
	.iter_mut()
	.map(|file| async move {
	match storage.delete(&file.1.location).await {
	Ok(_) => Ok(1),
	Err(e) => Err(ProtocolError::from(e)),
	}
	})
	.collect::<Vec<_>>();
