DeepSee.KPI enhancements

There are actually three suggestions, but they all relate to KPIs (link to what these are below).

%DeepSee.KPI

1. Provide the ability to change the number of rows displayed and exported for KPIs.

In scenarios where we create a table using KPIs, the number of rows always significantly exceeds 1000. It seems entirely appropriate to remove the row limit and provide the option to specify the row limit with a parameter.

2. Create a parameter for retrieving shared filters from the dashboard. In scenarios where a KPI doesn't have any filters defined but needs to retrieve them from the dashboard, there's no convenient parameter. Currently, %request.Content.FILTERS is used, but it retrieves filters in an unstructured array and in the MDX format [name].[hierarchy].[name].

3. In scenarios where a table is built using KPIs, add a "No data" placeholder for empty KPI data. Currently, only an empty table is displayed, without any user feedback. Hence user don't know what is wrong with the pivot.
