fix(botocore): [SVLS-5973] less noisy span pointers [backport 2.17]

[github-actions]

Backport ecd0ab1 from #11353 to 2.17.

Span pointer issues should be debug messages rather than warnings since they are not really actionable from the perspective of our users.

We'd also like to have some instrumentation telemetry to see how the logic is doing.
