added indexname to the toggle request interface

[sam0044]

Currently, there is a bug in the app where if you try to toggle off/on a specialization, the fields Document Count, Strictness, Past messages included and MaxTokenResponse revert back to default. The reason this is happening is because when we toggle the specialization, qSpecializationmutate only has the isActive field set and everything else is null. Because of that when we create the response, since the index name is null, the aforementioned fields are set to null because these fields should not be set without an index. This behavior is somewhat expected because we have a 'None' field in index name because of general being a specialization. So I am passing the index name in the Toggle request interface to distinguish between index being updated and just a specialization toggle.
