Review Comment:
   @rdblue @dramaticlly realized that `.` is still not properly handled. should 
we add extra check and fail if we receive namespace level containing `.` ? 
   
   inside `JdbcCatalog.createNamespace` we could check levels and ensure they 
don't containing `.` ? 
   other option is somehow escaping it. (Related to 
https://github.com/google/guava/issues/412)
   
   Example: `Namespace.of("test.Db");`
