This is a fairly simple patch that just adds a config command to get and set configurations similar to git config.
This would be very needed for higher level commands like kubeadm in order to gather stuff like the runtime-endpoint to query.

@feiskyer @Random-Liu PTAL

$ crictl config --get runtime-endpoint
/var/run/crio.sock

$ crictl config runtime-endpoint /var/run/dockershim.sock

$ crictl config --get runtime-endpoint
/var/run/dockershim.sock

$ cat /etc/crictl.yaml
runtime-endpoint: /var/run/dockershim.sock

Can we create an empty config here instead?

Agreed. We can create the default config file /etc/crictl.yaml if it doesn't exist.
