Add credentials auth for Google vertex

[eonghk]

Context

This pull request introduces credential-based authentication for Vertex AI, enabling users to easily switch between Google Cloud accounts.

• Simplified Account Switching:
  Users working across multiple Google Cloud projects can now seamlessly switch accounts without relying solely on Application Default Credentials (ADC). This eliminates the need for complex ADC management when using various profiles.

• Enhanced Flexibility:
  This feature benefits users who may not have the Google Cloud CLI installed or prefer direct credential management.

Implementation

• Added configuration options for Vertex AI authentication, allowing users to provide credentials through:
  • Directly pasting the JSON content of a service account key.
  • Specifying the file path to a service account key file (supporting JSON and other formats).
• Ensured compatibility with existing providers, maintaining their current functionality.
• Verified that Gemini models are also compatible with the new credential authentication method.

How to Test

• Ensure the Vertex AI API is enabled for your Google Cloud project.

• Verify that the desired Claude models are accessible.

• Create a new service account with the necessary Vertex AI permissions.

• Generate a service account key (JSON format recommended). Refer to the Google Workspace documentation for guidance: https://developers.google.com/workspace/guides/create-credentials?hl=en#service-account

• In the Vertex AI settings, paste the JSON content of the service account key into the "Google Cloud Credentials" field, or provide the file path to 'Google Cloud Key File Path' field.

• Execute a prompt to confirm successful authentication and model interaction.
