Repo maintenance for windows

[Lyndon-Li]

Fix issue #8419, support repo maintenance job to run on Windows nodes:

• Add toleration and labels to repo maintenance job pods
• Add retry to wait pod network ready
• Change repo maintenance job pod's TerminationMessagePolicy to TerminationMessageFallbackToLogsOnError, as kubelet has a bug to support TerminationMessageReadFile on Windows

Why do we need the indicator? Why cannot we return the termination message directly?

[Lyndon-Li]

The termination message is written to stdout together with logrus logs. So we use this indicator to identify it among other logs.

[Lyndon-Li]

As the behavior of TerminationMessageFallbackToLogsOnError, the last 2048 bytes of stdout is retrieved as the termination message whatever are there in the bytes.
