After switching to OVN-K we observed increase in memory resource and one
way to tackle it to have swap enabled on the node.
This PR is try to do following.
- Enable only `NodeSwap` feature gate instead complete Tech preview
features.
- https://docs.openshift.com/container-platform/4.15/rest_api/config_apis/featuregate-config-openshift-io-v1.html
- Add `swapaccount=1` to kernel argument which is required for the swap
- https://docs.openshift.com/container-platform/4.15/nodes/nodes/nodes-nodes-managing.html#nodes-nodes-swap-memory_nodes-nodes-managing
- Add swap feature to kubelet config
- Add systemd unit file to create swap and enable it
- Extend the disk size by 4GB because that much of space used for swap
Since 4.15 now released better to update the MIRROR and respective channel accordingly.
