kind infra, run etcd in memory

Currently we encounter bad performance of KIND cluster on DinD setup, we get 'etcdserver: timeout errors' that causes jobs to fail often. In such cases it is recommanded [1] to use in-memory etcd Running etcd in memory should improve performance and will make sriov provider more stabilized.
