Description

We use specifics encoder/decoder for our producers/consumers, they get correctly initialized by the Producer/Consumer. The only downside is the validate() function of VerifiableProperties that pollutes our log stream.

This patch allows custom serializers keys to validate correctly if they begin with the "external" prefix, for example:

external.my.encoder.param=true

will not raise a WARN.
