Feature: Feature flag for Direct approval story

[abhibhaw]

🔖 Feature description

Currently we always send direct approve button on email in case of:

1. config protection
2. Image Approval
3. Direct promotion

Which may not be acceptable for all the oranisations. We need to make this feature flag driven.

🎤 Pitch / Usecases

Only send direct approve button when this feature is enabled.

We will be needing separate control for all 3 approval emails (x approval emails in future), so better to plan this flag which can handle multiple approval cases.
