refactor: making account_link_processor pass through

[Karthick-Somasundaresan]

What

We are removing the need for determining the ProgressUnit and making account_link_processor a mere pass-through

Why

The distributor can decide on business logic to determine the unit type

How

It will pass the exact value that the application has shared to the distributor without inserting any business logic

Test

By manual testing
