Sybase metadata loading fails[1] when deploying dynamic vdb.

The problem is in JDBCMetdataProcessor.getForeignKeys. Method loads FKs from all tables, but it fails when it tries to load FKs from table sysquerymetrics. The problem seems to be that sysquerymetrics is not a system table, it is a view.

[1] Reason:TEIID11010 com.sybase.jdbc4.jdbc.SybSQLException: No such object or user exists in the database.
