• Feature

Which issues of this PR fixes ：

When importing the primary key table, it supports ignoring deleted Row data, that is, changing DELETE to UPSERT. Especially in the case of FLink-CDC, when these parameters are turned on, the complete data can be retained when imported into Starrocks.

Pull Request Overview

This PR adds support for ignoring delete operations when importing data into primary key tables by introducing a new sink.ignore.delete configuration option. When enabled, DELETE operations are converted to UPSERT operations, which is particularly useful for Flink-CDC scenarios where complete data retention is desired.

Key changes:

• Adds new configuration option sink.ignore.delete with default value false
• Updates transformer interfaces and implementations to accept the new ignoreDelete parameter
• Modifies transformation logic to convert DELETE operations to UPSERT when the option is enabled
