[dbm] fix flapping sqlserver_version

[ynnadkrap]

What does this PR do?

We received customer reports about missing sqlserver_version. The problem is that we store the version in a cache that has a 1 day TTL, and we never refresh the cache. The fix is to refresh the cache during each check run.

You can see the problem here where I changed the TTL to 5 minutes:

Motivation

Additional Notes

Review checklist (to be filled by reviewers)

• Feature or bugfix MUST have appropriate tests (unit, integration, e2e)
• Changelog entries must be created for modifications to shipped code
• Add the qa/skip-qa label if the PR doesn't need to be tested during QA.
• If you need to backport this PR to another branch, you can add the backport/<branch-name> label to the PR and it will automatically open a backport PR once this one is merged
