Batching strategies

[katelashkevich]

For every target activity in the transitions with WT due to batching, we need to identify what batch processing strategy is applied in that activity. More specifically, we need to identify:

1. activities in which batch processing is applied (i.e., target activities);
2. frequency of batch processing (i.e., percent of cases for which batching is applied from the total number of cases processed in the activity);
3. batch processing type;
4. batch activation rule;
5. batch activation rule quality;
6. batch size distribution.

There is no need to develop the code for this functionality from scratch as it is already developed by David (see https://github.com/AutomatedProcessImprovement/batch-processing-discovery). Here, we need to re-use it.

The requirements for the UI for this component will be specified in a separate ticket.

FYI
Here, we also need to know which resources apply batch processing and how much WT due to batching each of them induces in each transition. This is already available in Kronos.
