Subject: [PATCH] Set CPUManagerPolicy=static, reserve compute resources

Fixes: #8, #16

Setting CPUManager=static allows `Guaranteed` QoS class workloads to
get cpu isolation and affinity benefits.
https://kubernetes.io/blog/2018/07/24/feature-highlight-cpu-manager/

Setting reserved compute resources for system processes and critical
kube components prevents from DoS'ing the compute node.
