Problems with Constants, Low Severity 1

	Change	Effect
1	The value of constant RD_KAFKA_DEBUG_CONTEXTS has been changed from "all,generic,broker,topic,metadata,queue,msg,protocol,cgrp,security,fetch,feature" to "all,generic,broker,topic,metadata,feature,queue,msg,protocol,cgrp,security,fetch,interceptor,plugin,consumer".	Applications will pass an old value of this constant as the parameter to the new-version library functions, that expect a new one. This may result in crash of incorrect behavior of applications.
