Permissions don't work with virtual procedures' ResultSet

Teiid doesn't work with ResultSet of a virtual procedure. For example, if we have procs.testProc virtual procedure which can return two values in ResultSet: a and b and we specify a permission for one of these columns in ResultSet, the permission won't work:

        <permission>
            <resource-name>procs.testProc.a</resource-name>
            <allow-read>false</allow-read>
        </permission>

I think it would be great to set permissions also for ResultSets of virtual procedures, so AuthorizationValidationVisitor.validateEntitlements method for a GroupSymbol, which is a procedure, should analyze also its ResultSet. At the same time permissions work for virtual views and we can set permissions for some views' columns separately.
