Hi, this is a very simple demo that illustrates the overall idea. The are
some issues that need to be discussed.
1. Madsim has already provided a wrapper for aws-sdk-s3 crate, something
like this:
```rust
#[cfg(madsim)]
#[path = "sim.rs"]
mod sim;
#[cfg(not(madsim))]
pub use aws_sdk_s3::*;
#[cfg(madsim)]
pub use sim::*;
```
Should we reuse the S3 simulation logic from the madsim wrapper or develop
our own?If we use madsim's simulation, since the interface simulated by madsim
and that of aws-sdk-s3 are the same, we need to use that interface to implement
our `Accessor` trait. If we choose to develop our own simulation logic, we need
to completely eliminate uncertainty, such as multi-threaded scheduling(seems a
lot of work).
2. Can different backends use the same simulation? For example, S3 and OSS
may be similar, but I'm not sure.
