feature: systemd overrides for rke2-server and agents

[michalg91]

Summary

We've got some large master nodes which are having large etcd database and during upgrade when rolling restart occurs there can be timeouts on restarting service. It will fail on node and start restarting next one, which is not wanted.

what we can do here is:

• ignore this error and add another task with retry to check if unit is started
• add ability to provide override.conf for service with eg. extended timeout (TimeoutSec,TimeoutStartSec).

Hi @michalg91, according my knowledge rke2-server service has TimeoutStartSec=0 so there is no timeout. But I think that failed rke2-server restart should actually stop the whole playbook and not to continue to another node - so this is something which could be improved.
