feat: Add annotation to tweak providedThroughput control for tables

[pbarsotti-glovo]

Issue 2032.

Description of changes:

Following the line of what was implemented for NodeGroups in this PR, the idea is to allow users to indicate via an annotation if the provisioned throughput of a table is managed by ACK's controller or if an external autoscaler is adapting the capacity dynamically.

In case of external autoscaler, the provisioned throughput defined in the spec is ignored during the delta creation phase to avoid updating these values, which could result in a sudden loss of capacity.

Hi @pbarsotti-glovo. Thanks for your PR.

I'm waiting for a aws-controllers-k8s member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

hey @a-hilaly the codgen diff in the version could be due to my ack_generate_info version?

For DynamoDB Tables we have multiple fields where provisioned throughput values are defined and can be managed externally. For example, spec.globalSecondaryIndexes, spec.tableReplicas, and tableReplicas.globalSecondaryIndexes can each have their own provisioned throughput values set. Should these fields also all be managed by this annotation as well or do we need more fine-grained control here?

I thought that could be better to handle each one independently, although following the same approach. That's why I put Table as part of the annotation, so different ones could be created for the rest of the cases.
