Add flow around controlled moving cylinder (coupling FMI with OpenFOAM)

[uekerman]

I took the original case of @LeonardWilleke from https://doi.org/10.18419/darus-3549, ported it to v3, and made it "tutorials-ready" (shorter runtime, README, ...). We should make @LeonardWilleke a co-author when merging here.

I ran the case with the precompiled FMU, I did not try to recompile on any other system.

Some first comments on the general tutorial aspects (looks good already, needs some minor cleanup).

I have not yet tried to run it, and I don't have the expertise to review the FMI part.

Update: I can run the case, even though it takes quite a while (I am already running for several minutes, and I am only at 10%). Is there anything we can do to speed it up, or just reduce the simulated time?

edit: Takes around 70min to complete on my laptop.

Writing in the README:

To reduce the overall runtime compared to the original contribution, this case uses a larger time step size 2.5e-3 (instead of 1e-3) and the controller switches on at t=2 (instead of t=40). Still, the scenario requires around an hour to complete.

I already tweaked there a lot. The original case ran overnight.

Apart from the few open questions that might need more documentation (but definitely need help from @LeonardWilleke), this looks ready from my perspective.

@uekerman feel free to merge once everything is clear.
