[IMP] mis_builder: provide more views in drilldown

Prior to this commit only the `tree` and `form` views where made available
while drilldowning in the `mis.report.instance` preview.

After this commit if available, the `tree`, `form`, `pivot` and `chart` views
will be provided.

The available views and orders can be easilly overriden.
