connects to basin w3s service

[brunocalza]

This PR updates the provider to make a call to https://github.com/tablelandnetwork/basin-w3s when a file is uploaded

It also does some cleaning up:

• removes old RPC cold
• and any unnecessary old web3 storage code

[brunocalza]

new flag to indicate where the server is located. right now it's a private server inside kubernetes reachable at basin-w3s.basin-staging.svc.cluster.local:8080

[brunocalza]

changes the web3 storage client to make a call to the service. It returns a UploadResponse object

[avichalp]

one suggestion on naming. what do you think about naming the trait as Web3Storage and the struct as Web3StorageClient?

[brunocalza]

sounds good!

👍

Looks good

Maybe good to move the retry part into a different function? because this expressions looks quite complicated to read. For example:

pub async fn upload_w3s_with_retry<W: Web3Storage>(
    filename: &String,
    gcs_client: GcsClient,
    w3s_client: W,
) -> basin_common::errors::Result<Vec<u8>> {
    let mut retries = 0;
    loop {
        let result = upload_w3s(gcs_client.clone(), w3s_client.clone(), &filename).await;
        if result.is_ok() || retries > 3 {
            break result;
        } else {
            retries += 1;
            tokio::time::sleep(std::time::Duration::from_millis(100)).await;
        }
    }
}

 let cid_bytes = match upload_w3s_with_retry(&filename, gcs_client, w3s_client).await {
        .....
    };

Totally! This should be in the web3 client actually, transparent to this part of the code, but was having a hard time getting the code to compile haha anyway, this was just a test to see if retrying would fix the problem of uploading big files, but I actually found out what the problem was. I'm going to remove it, actually
