[Bug]: UserWarning about deprecation of boundaries with "lettuce benchmark" and other usecases #296
Description

No response
What happened?
When calling lettuce benchmark in command prompt and/or several other lettuce-functionalities, lettuce issues a UserWarning on deprecation of "boundaries" due to the new "post_boundaries" and "pre_boundaries" feature. So the flow that is used for "lettuce benchmark" seems to not implement boundaries in the currently accepted way.
The benchmark still runs, tho... (see log output below)
Version
0.2.0
What operating system are you seeing the problem on?
