new feature: Build opendal Operator via object_store's Options

[Xuanwo]

Feature Description

object_store_opendal enables users to utilize opendal as object_store::ObjectStore. Consequently, we can facilitate the construction of the opendal Operator through the object_store's Options, allowing users to employ the same configuration pattern consistently.

Problem and Solution

Some object_store users heavily rely on the Options input of object_store. We can use these options to directly build an opendal Operator, thereby simplifying their experience.

Could you clarify what the object_store options refer to? GetOptions and PutOptions ?

Hi, I'm talking about the config key like: https://docs.rs/object_store/0.11.1/object_store/aws/enum.AmazonS3ConfigKey.html

I haven't figured out how to use these options to directly build an opendal Operator. I have two thoughts:

1. Provide an object_store::S3Builder which implements opendal::Builder, allowing users to construct an opendal::Builder using config keys in AmazonS3ConfigKey
2. Write a helper function to convert AmazonS3Builder into opendal::Builder

Do you have any other ideas ?

I'm thinking of an object_store_opendal::AmazonS3Builder that returns object_store_opendal::ObjectStore. It don't need to play with opendal::Builder directly.

Ok. Let me give it a try.
