Hide Objects that a User has no privileges to in the DV Metadata

Issue

• Is there is a way to hide individual objects that a user doesn't have permissions to in the metadata
• TEIID-2476
  • Exclude hidden tables/columns from metadata
  • We should offer or possibly default to filtering tables/columns that can not accessed out of the user metadata. This should be done on the server side - however given the reuse we have of the system tables for example for materialized pg catalog queries - it is easier to add filters to the DatabaseMetadata (and ideally pg) metadata queries.
