Since coil is built using kubebuilder and controller-runtime and they have not used client-go of k8s 1.19 yet, we cannot upgrade client libraries for k8s 1.19.
Add k8s 1.19 to the matrix of CI and fix problems if any.
Upgrade the container base image from Ubuntu 18.04 to Ubuntu 20.04.
Use Go 1.15 to build binaries.
What
Add support for Kubernetes 1.19.
