Bunny drill fix

[blaisb]

Description of the problem

• The bunny drill example was broken since the change to Solid Object which were now restarted

Description of the solution

• Fix the problem by adding the bunny from the onset of the problem. However, this required changing insertion mechanism. I used this opportunity to demonstrate the plane insertion as part of an example. I think it's a cool idea.
• For a reason I don't know, the time-step was way too small. Updated it to a more coherent value, the simulation is much faster now (like 10 minutes or so)

How Has This Been Tested?

• Example was re-run and identical results are obtained

Documentation

• Documentation is updated accordingly since we change the insertion mechanism

Comments

Working on this I found another bug. Right now the example will not work correctly if there are no load balancing steps. It seems to be related to the way the objects are displaced and the displacement monitoring is made after the checkpointing. I will use this example to work on fixing this bug, but this will be work this week in a next PR.

Closes the issue in #1129

I think the time step was small because of the rotation of the solid object.

Big time steps had a tendency to deforme the bunny...

Yeah but 1e-5 does not deform the bunny at all. I think it is because we designed the test when we still had some bugs with solid objects that were fixed down the road.
