[teiid-designer-issues] [JBoss JIRA] (TEIIDDES-1739) Refactor DdlImporter into dialect-specific processors.

Refactor DdlImporter into dialect-specific processors. ------------------------------------------------------ Key: TEIIDDES-1739 URL: https://issues.jboss.org/browse/TEIIDDES-1739 Project: Teiid Designer Issue Type: Feature Request Components: Import/Export Affects Versions: 8.2 Reporter: Barry LaFond Assignee: Paul Richardson Priority: Blocker Fix For: 8.2 Current DdlImporter handles multiple DDL dialects, including the new Teiid-related modifications. Refactor this class to allow dialect-specific implementations of an Interface that can be handed an AstNode and either process the node, or not. Also need to allow for handing off Teiid-DDL Options to the Extension Assistants to inject the extension properties into the models. This is currently not handled correctly
