Description

Feature request

Overview

Currently, Delta SQL configuration properties (link) are prefixed with spark.databricks.delta.

We should refactor this to be only spark.delta, while still maintaining support for legacy spark.databricks.delta usages.

Motivation

Delta Lake is an open-source project and we should clean up + refactor code (especially public-facing APIs like a SQL conf) to remove any references to databricks.

Contributor guide

Research direction
Identify all configuration keys prefixed with `spark.databricks.delta` in `DeltaSQLConf.scala` and elsewhere, then create a mapping to new `spark.delta` keys while implementing a fallback for legacy keys. Update all references and ensure existing tests pass.
