flowable-ui without history

**Problem description:**
flowable-ui applications allows to work only with the history level `AUDIT`. `NONE` and `ACTIVITY` history levels are not supported.

**Describe the solution you'd like**
Based on `flowable.history-level` property adjust frontend and backend behavior to allow querying for other history levels.

**Describe alternatives you've considered**
Another possibility could be to create a separate app for different history levels. (less convenient than proposed solution)

**Additional context**
Let me know whether there is an interest to allow such a functionality in flowable.
