## Include and exclude tokens support

Requirement
- Support for always include tokens 
    -  When a user gives tokens as **always include** those tokens will be always included when he creates a collection.
- Support for marking an token for **exclusion**, similar to the below image.

- These reports for exclusion will be montiored by  a superuser. Only when the superuser approves the token to be excluded then only it will be excluded. ( Need new UI for this page)

- Support for invalid tokens 
    - When an user gives some tokens as **invalid** than those tokens will not be considered when the collection is getting created.
