Add OpenAI Integration

[adamfisher]

This issue tracks the implementation of an integration for OpenAI (DALL-E & ChatGPT) in Elsa Workflows. The module should allow workflows to interact with OpenAI services, including text generation, image creation, transcription, translation, and batch processing.

• Implement Workflow Activities:

  • AddFilesToVectorStore - Adds files to a specified vector store or creates a new one based on configuration.
  • AnalyzeImagesVision - Analyzes images according to specified instructions.
  • CancelBatch - Cancels an "in-progress" batch, which will transition to "cancelled" after up to 10 minutes.
  • CreateBatch - Creates and executes a batch of API calls.
  • CreateCompletion - Generates a completion for a given prompt using GPT models.
  • CreateModeration - Determines whether an image or text contains violent, hateful, illicit, or adult content.
  • CreateTranscription - Converts an audio file to text using Whisper.
  • CreateTranslation - Translates an audio file into English using Whisper.
  • EditImage - Edits or extends an image using DALL-E.
  • GenerateAudio - Produces an audio file based on text input and settings.
  • GenerateImage - Creates an image using DALL-E.
  • GetBatch - Retrieves details of a specified batch.
  • ListBatches - Retrieves a list of batches.
  • MakeAPICall - Performs an arbitrary authorized API call to OpenAI services.
  • MessageAssistant - Sends messages to a specified or newly created thread and executes it seamlessly with Assistants v2.
  • TransformTextToStructuredData - Extracts structured data from a prompt’s text.
  • UploadFile - Uploads a file for use across the OpenAI platform.
  • WatchBatchCompleted - Triggers when a batch process is completed.
