[RFE] Cannot retrieve agent logs without container access

[Jim Rollenhagen]

When errors happen, it would be great to have agent logs. However, this currently requires SSH and/or console access to the agent image. The agent should ship these logs somewhere in order to make viewing them easy.

Note that this is likely to require a spec.

Yes, this is useful function to debug/diagnose the agent side issue.
I have an idea here, can we enable the OS level serial redirection in both DIB and our pxe configuration, then after agent kernel started, all the os level stand output can be redirected to serial, and our IPMI can get these output, then we run command to open the console to monitor the output. Any comments?

DIB has such enable serial console element already:

Changing PRI to Wishlist
- this doesn't represent a loss in service functionality for users
- as previously noted, the implementation should go through a design review

We support agent logs, don't use a container, and it's 2023.
