Log warning when param is not annotated with @ProjectedPayload (4.0.x) #3300
Description
Introduce a warning log if a parameter is not annotated with @ProjectedPayload that this style is deprecated and that we will drop support for projections if a parameter is not annotated with @ProjectedPayload.
Also, add this detail to "Deprecations" section of docs/release notes.
Note
Implementation notes:
- Avoid log spamming: only log the warning once per param (or maybe drop down from warn to debug)
- Allow users to disable the logging via the typically logging config
