AWS SDK v2 implementation of table properties save/load

[patchwork01]

Background

Split from:

• Standardise on using AWS SDK version 2 everywhere #1389

Reopened from:

• Support use of AWS SDK v2 in Instance and Table Properties #629

Description

We'd like to be able to use version 2 of the AWS SDK to load and save the Sleeper table properties.

Analysis

We can make a straight copy of the integration tests, using the V2 SDK instead. The integration tests that use this code indirectly can be moved over to the V2 version gradually as we convert each part of the code to use it. Once everything uses the new V2 version, we can delete the old tests and code for V1.

We don't need to update anything that uses this code as part of this issue. If we spot any cases where we have an AWS SDK v2 implementation of everything that's wired in, e.g. for a lambda or an ECS task, we can move the whole lambda or ECS task over at once. We could do that as soon as we spot somewhere we have a v2 implementation of everything. We can split out separate issues for that.
