feat: partial batches

[QuantumExplorer]

Issue being fixed or feature implemented

In RS-Drive atomicity of state transitions is paramount. A state transition is a collection of multiple operations that often will cause one or more identity balances to change. The amount that the identity balance must change by is driven by costs of changes in the batch. Ideally we should be able to alter the batch by adding operations based on calculated information coming from the batch itself.

For example in one batch have the document insertion, but also the reduction of credits of the identity due to the document insertion.

What was done?

To be able to perform this feature, we need to get back costs from an insertion, then perform just in time updates to the batch, this is what is coded up in this PR.

How Has This Been Tested?

Added some unit tests
