GitHub runners provide 14GB of guaranteed available disk space, which is typically sufficient for running k0s's integration tests. However, when free space drops below 15%, Kubernetes initiates pod eviction, leaving only 5GB left on an 84GB disk until it kicks in. In response, streamline disk space usage and remove non-essential data. That's easier than globally overriding Kubernetes eviction defaults for all integration tests.

Description
GitHub runners provide 14GB of guaranteed available disk space, which is typically sufficient for running k0s's integration tests. However, when free space drops below 15%, Kubernetes initiates pod eviction, leaving only 5GB left on an 84GB disk until it kicks in. In response, streamline disk space usage and remove non-essential data. That's easier than globally overriding Kubernetes eviction defaults for all integration tests.
Also revert #3470 which was another workaround that solved the problem for a single integration test.
