Run drenv cluster tests

On macos-13 runner we can run the test cluster using nested
virtualization. Build and install lima and socket_vmnet, and add the
missing steps to start the test cluster and run all the tests, including
cluster tests.

We may want to make the kubernetes ready timeout configurable, since
locally it completes in few seconds, but it time outs with 10 minutes
timeout on github action.
