Improve the user experience when Teiid JDBC connection info is NOT saved and Designer is restarted

If user creates a new Teiid Server instance and does NOT check the "Save" JDBC connection info (password), preview data and execute VDB will work during this session of Designer.

If user exists and restarts, the password is empty and any Preview Data action or Execute VDB action will result in a Teiid connection exception and a dialog will be displayed.

Would be really nice to be more "proactive" and maybe warn the user prior to executing? or add a "problem" marker for the Teiid Server, and or decorate the Teiid Server with a Warning/JDBC icon?
