6181 workflows create a custom code executor (#6235)

Closes #6181

## Testing
- download Altair graphql dev tool https://altairgraphql.dev/#download
- create a file locally `test.ts` containing:
```
export const handler = async (event: object, context: object) => {
  return { test: 'toto', data: event['data'] };
}
```
- play those requests in Altair:
mutation UpsertFunction($file: Upload!) {
  upsertFunction(name: "toto", file: $file)
}

mutation ExecFunction {
  executeFunction(name:"toto", payload: {data: "titi"})
}
- it will run the local driver, add those env variable to test with
lambda driver
```
CUSTOM_CODE_ENGINE_DRIVER_TYPE=lambda
LAMBDA_REGION=eu-west-2
LAMBDA_ROLE=<ASK_ME>
```
