RH Subscription: disable relevant actions in manifest modal when a task is in process
Instead of disabling the entire manifest modal popup just disable those actions that should be disabled:
- Refresh manifest
- Delete manifest
- Upload manifest
If we are in disconnected mode or a task is in progress we need to
disable ability to add subscriptions, delete subscriptions,
edit/modify subscriptions, and refresh manifest.
Also fixes the manifest modal table after the changes to indices.
