* Revert "Apply Jackson stream read constraints defaults at runtime (#16832)"
This reverts commit cc608eb88b.
* jackson stream read constraints: code-based defaults
refactors stream read constraints to couple default values with their
associated overrides, which allows us to have more descriptive logging
that includes provenance of the value that has been applied.
