[Bug] Smoketest recording downloads via S3 presigned URL stopped working

[andrewazores]

Current Behavior

1. ./smoketest.bash -gt
2. Select a target, ex the localhost:0 one
3. Create a new recording
4. Click the recording's menu, then Download recording

This used to work and result in the recording .jfr and .metadata.json being downloaded to the client. At some point recently this broke - the .metadata.json still appears (since it is actually generated on the client side rather than downloaded from the server), but the request to download the recording file from the S3 provider (cryostat-storage/SeaweedFS in this case) fails with an HTTP 403 Forbidden and a response body indicating that the request signature did not match.

I suspect this has to do with how I put together the external storage URL handling for the case where storage is behind a proxy. The presigned request signature includes information about the host it is valid for, so using a proxy's hostname will fail the signature check.

I tried running the smoketest with an older storage container image and the behaviour was the same. Nothing else has changed in a while so I'm not sure what is happening. The only other difference is I'm running this on my laptop instead of my desktop - it would be strange if that was the cause but I will test again on my desktop later on.

I've implemented a workaround, but ideally this should actually work as intended with presigned URLs.

Closing, presigned URLs are not used like this in 3.0 For the next release it would be a good goal: #269
