docs: admin-guide: add a series of orphaned documents

There are lots of documents that belong to the admin-guide but
are on random places (most under Documentation root dir).

Move them to the admin guide.

Clearing WARN_ONCE
------------------
WARN_ONCE / WARN_ON_ONCE / printk_once only emit a message once.
echo 1 > /sys/kernel/debug/clear_warn_once
clears the state and allows the warnings to print once again.
This can be useful after test suite runs to reproduce problems.
