[teiid-designer-issues] [JBoss JIRA] (TEIIDDES-2079) Add valdiation of REST extension properties for virtual procedures

Add valdiation of REST extension properties for virtual procedures ------------------------------------------------------------------ Key: TEIIDDES-2079 URL: https://issues.jboss.org/browse/TEIIDDES-2079 Project: Teiid Designer Issue Type: Enhancement Components: Modeling, Validation Affects Versions: 8.4 Reporter: Barry LaFond Assignee: Barry LaFond Fix For: 8.5 The recognition of REST extension properties keys off of both REST METHOD and REST URI properties either both being present or both null. Workspace Validation: Create a RestPropertiesValidationRule to create a problem marker if this is not the case Procedure Wizard validation: * Add CHARSET and HEADERS property Widgets to ViewProcedureEditorPanel * Add charset and header instance variables to RelationalViewProcedure object (include getter/setter methods) * Add validation to ViewProcedureEditorPanel to verify the same. Thinking in both instances we should default the severity to WARNING and not error.
