Include "BatchApex" in template options for apex generate class

[k-capehart]

For the apex generate class command the template options are: ApexException | ApexUnitTest | BasicUnitTest | DefaultApexClass | InboundEmailService.

I think it would be useful to include an option for an Apex class that implements the Database.Batchable<sObject> interface.

I believe we just need to include the template in this repository, and then add the option in the CLI.

The template would look something like this:

public with sharing class <%= apiName %> implements Database.Batchable<sObject> {
  public <%= apiName %>() {

  }

  public Database.QueryLocator start(Database.BatchableContext bc) {

  }

  public void execute(Database.BatchableContext bc, List<sObject> scope) {

  }

  public void finish(Database.BatchableContext bc) {
  
  }
}

Is this something people think would be useful?
