The automated MetalLB tests involve installing the MetalLB operator during setup, and removing it at teardown.

The operator removal on teardown results in cordoning nodes (for a reason we still don't know), and therefore many of the following tests fail.

We should either investigate whether this long-time cordoning is a bug, or fix the tests with a wait for all the nodes to become schedulable again (which might be tricky, because the cordoning doesn't happen immediately, but rather a few minutes after the operator removal is done).

Until then - MetalLB tests shouldn't run.

Update 2024-Mar-20:
The solution we will implement is:

• On setup: Check if metallb is already installed, and install it if not.
• On teardown: Don't uninstall metallb.
