Refactor defer-close with error handling

[facuMH]

This PR contributes to https://github.com/Fantom-foundation/sonic-admin/issues/90

This PR adds real life use cases of both functions provided the caution package to properly handler errors in case of defer and close.

This PR fixes some of the unhandled errors reported by the external audit. Most (if not all) of them are from either defer close patterns or similar cleanups or unhandled close errors.

Test list to verify we don't have double closes (or other errors) and panic now because error is no longer ignored:

• run make test
• Norma test
  • demonet/static.yml
  • demonet/dynamic.yml
• testing suggestions ?

I saw some details that need handing;

Additionally, I would like to avoid using caution.CloseAndReportError for scenarios without defer, it does nonstandard error handling, and it may be a little convoluted to read. We can talk about a replacement.
