async version of Resource Proxy getURL

[charlesritchea]

Feature

As everyone should know AWS SDK v2 is going away and we should all move to v3

In our implementation of Cesium/Resource/Proxy.getURL we use the v2 aws sdk

s3.getSignedUrl('getObject', {
        Bucket: s3Object.bucket,
        Key: s3Object.key,
        Expires: 86400 // 24 hours
})

In v2, this is a synchronous method and works in getURL.
However in v3, The only solution I could find is async.

Can you make getURL async? Or is there an alternative to this class?

Hi @charlesritchea, using a promise within getUrl is not currently supported. Though I would say this is related to some cleanup we'd like to do for the entire Resource class to make better use of async code paths.

Yes, that's why this is a feature request. :) Glad to see it's being considered, but wanted to let you know this is forcing people to use the abandoned sdk

Got it, thanks @charlesritchea!
