[feat] Option to generate enum with full prefix

[Thu Vo]

For example, the code below is generated from buf:

/**
 * @generated from enum usermgmt.common.ImportUserEventStatus
 */
export enum ImportUserEventStatus {
  /**
   * @generated from enum value: IMPORT_USER_EVENT_STATUS_WAITING = 0;
   */
  WAITING = 0,

  /**
   * @generated from enum value: IMPORT_USER_EVENT_STATUS_FINISHED = 1;
   */
  FINISHED = 1,

  /**
   * @generated from enum value: IMPORT_USER_EVENT_STATUS_FAILED = 2;
   */
  FAILED = 2,
}

However, in the backend (BE) code, the definition is as follows:

enum ImportUserEventStatus{
  IMPORT_USER_EVENT_STATUS_WAITING = 0;
  IMPORT_USER_EVENT_STATUS_FINISHED = 1;
  IMPORT_USER_EVENT_STATUS_FAILED = 2;
}

The question arises: Instead of generating and stripping out theprefix, should we consider adding opts to generate with the full key, such asIMPORT_USER_EVENT_STATUS_FAILED instead of justFAILED?

This consideration is important because when storing data in the database, it uses the full name (IMPORT_USER_EVENT_STATUS_FAILED) instead of the stripped-out version.

Using the full key ImportUserEventStatus[key] in the code makes it easier for mapping between the number and key instead of using longer methods like proto3.getEnumType(ImportUserEventStatus).findName(<value>).

I also post my question in Slack before https://bufbuild.slack.com/archives/CRZ680FUH/p1699259433760749

Hi @vctqs1! This would be a good feature request to open in the protobuf-es repo, which generates the code in your example.

@smallsamantha Ah thank you. Sorry for the inconvenience
