KAFKA-7663: initial commit for reprocessing on user added stores

[wcarlson5]

When custom processors are added via StreamBuilder#addGlobalStore they will now reprocess all records through the custom transformer instead of loading directly.

We do this so that users that transform the records will not get improperly formatted records down stream.
