Support get_multi_ranges in ObjectStore

[Ted-Jiang]

Is your feature request related to a problem or challenge? Please describe what you are trying to do.
now we have

arrow-rs/object_store/src/lib.rs

Lines 115 to 118 in 6c3f9a2

	/// Return the bytes that are stored at the specified location
	/// in the given byte range
	async fn get_range(&self, location: &Path, range: Range<usize>) -> Result<Bytes>;

I found in #2110 already support multi ranges

arrow-rs/parquet/src/arrow/async_reader.rs

Lines 115 to 124 in aeb2776

	/// Retrieve multiple byte ranges. The default implementation will call `get_bytes` sequentially
	fn get_byte_ranges(
	&mut self,
	ranges: Vec<Range<usize>>,
	) -> BoxFuture<'_, Result<Vec<Bytes>>>
	where
	Self: Send,
	{
	async move {
	let mut result = Vec::with_capacity(ranges.len());

we should support same location path with multi ranges read in object_store,

like

async fn get_ranges(&self, location: &Path, range: &[<usize>]) -> Result<Bytes>; 

This will reduce some overhead like in HDFS:
We need to get file metadata for each location from metadata server(nameNode), if we can get multi ranges in one location will reduce some rpc call in system.

@alamb PTAL 😊

Perhaps

async fn get_ranges(&self, location: &Path, ranges: &[usize]) -> Result<Vec<Bytes>>; 

With a default serial implementation?

Sure!
