Currently, RelSchemaConverter which converts Sql schema to Calcite schema

Currently, RelSchemaConverter which converts Sql schema to Calcite schema
always marks the fields as nullable regardless of nullable flag in Sql schema.
To address this problem, we need to first fix all RelSchemaProviders to
accurately represent the fields with the right structure (Linkedin specific
