Update PRD:Allow modprobedDir together with modulesLoadingOrder - #1887
Conversation
Supersedes the mutual-exclusion decision in rh-ecosystem-edge#1319. The combination must not be rejected. If a user file collides with KMM's loading-order file, the module fails to load instead of overwriting silently. This is a manual cherry pick for this upstream.

mounts only softdep.conf as read-only, using a file-level subPath or equivalent
staging approach, while leaving the modprobedDir-unset behavior unchanged.
Ensure user-provided files remain visible in /etc/modprobe.d, and add
integration coverage for both files plus failure before modprobe when the source
includes softdep.conf.

Mount only softdep.conf.
When both capabilities are enabled, setWorkerSofdepConfig mounts the DownwardAPI volume at /etc/modprobe.d as read-only. This hides the user files that the enhancement requires at that path.
Use a file-level mount, such as subPath, or an equivalent staging design. Preserve the existing behavior when modprobedDir is unset. Add an integration test for both files and for failing before modprobe when the source contains softdep.conf.
