This eliminates use of the deprecated AWS SDK v1, migrating entirely to SDK v2. This also implies an update from HTTP client v4 to the current v5.

The migration revealed a few problems in the single point proxy timeouts and the census data uploader, which have been resolved. The problems and their fixes are described in the commit messages and inline code comments.

This will be followed by a corresponding update to the cluster deployment code.

Maintain older executeOpen style for single point proxy in broker.
Migrate both to try-with-resources.
This should eliminate some edge cases with unanticipated exceptions.

Switch seamless census uploader to buffer tiles before uploading to S3.
