Refactor system vdb
-------------------

                 Key: TEIID-871
                 URL: https://jira.jboss.org/jira/browse/TEIID-871
             Project: Teiid
          Issue Type: Sub-task
          Components: Query Engine
    Affects Versions: 6.3
            Reporter: Steven Hawkins
            Assignee: Steven Hawkins
             Fix For: 6.3

1. We should remove the system physical model - it's undocumented, exposes too much metadata cruft, and requires too much logic in the index connector to support it.
2. We should remove System.datatypeelements and System.datatypeelementproperties - the transformations are invalid (they will always return no rows) and they are redundant 
3. There should be a new system table ProcedureParamProperties that exposes annotations for procedure params.
with System.element/datatype and the corresponding properties tables.
4. This one is open to debate, but I would also like to remove System.describe - since annotations are available directly on the appropriate type table, there doesn't seem to be a good reason to introduce a procedure that operates over all metadata records to return the same information.
