Add a new e2e test clusterctl_upgrade_test to testing upgrading from v0.2.0 to current version (built from source)
In complement to inplace_rollout_test, the clusterctl_upgrade_test will also include scenarios for modifying cluster labels/ annotations after upgrade, to verify SSA patch (#136 ) is working as expected if user upgrade from an old version k3s CAPI.
Running e2e with tilt is broken (as I need to remove v1.8.99 from e2e setting, otherwise clusterctl_upgrade_test is not functioning), remove that part in e2e README.
