Description

Migrate the existing thresholds for logged/unlogged batches:

batch_size_warn_threshold_in_kb: 5
batch_size_fail_threshold_in_kb: 50
unlogged_batch_across_partitions_warn_threshold: 10

To a pair of new guardrails under the guardrails section, for example:

guardrails:
    ...
    batch_size:
        warn_threshold_in_kb: 5
        abort_threshold_in_kb: 50
    unlogged_batch_across_partitions:
        warn_threshold: 10

At the moment these thresholds are enabled by default, while guardrails are globally disabled by default, so we should consider whether we want to globally enable guardrails, or change these thresholds to disabled by default, or don't migrate the thresholds.
