[Bug 1397310] [NEW] Attribute validation errors are logged twice

 

Public bug reported:

In neutron/api/v2/attributes.py, all validation functions debug-log any
errors that occur inside them, and return the error message back to
caller. In the end, those messages get into _validate_dict() function
that also logs those messages, if any. Meaning, we'll get duplicate
validation errors in debug logs for every validation failure.

Validation functions should not report those messages themselves,
instead relying on caller to handle returned error messages as it sees
fit.
