[doc] 4.10.7.2 Renewing Certificates Created -> why /etc/kubernetes/pki.bak ?

4.10.7.2 Renewing Certificates Created by skuba:

https://susedoc.github.io/doc-caasp/master/single-html/caasp-admin/#_renewing_certificates_created_by_skuba

For this process I would recommend to use the skuba cluster directory on the admin node and not /etc/kubernetes/pki.bak

--> /etc/kubernetes/pki.bak does not exist on the admin node and would also not be writeable as non-root user.

So can we change the paths, here?

[jenting]

Because we based on the assumption that the admin login into one of the control plane nodes, so we suggest backup the certificate in /etc/kubernetes/pki.bak.

And yes, we could change to back up the certificates in the admin node.
