kubelet: Expose simple journald and Get-WinEvent shims on the logs endpoint
Provide an administrator a streaming view of journal logs on Linux
systems using journalctl, and event logs on Windows systems using the
Get-WinEvent PowerShell cmdlet without them having to implement a client
side reader.

Only available to cluster admins.

The implementation for journald on Linux was originally done by Clayton
Coleman.

Introduce a heuristics approach to query logs

The logs query for node objects will follow a heuristics approach
when asked to query for logs from a service. If asked to get the
logs from a service foobar, it will first check if foobar logs to the
native OS service log provider. If unable to get logs from these, it
will attempt to get logs from /var/foobar, /var/log/foobar.log or
/var/log/foobar/foobar.log in that order.
The logs sub-command can also directly serve a file if the query looks
like a file.
