tools: add qm-storage-settings

[dougsland]

setup calls storage() function to execute the initial storage configuration but it's not called during the ostree deploy as it's required to call /usr/share/qm/setup. This patch extract the logic from setup with few improvements and now can be called externally via ostree / osbuild / osbuild-auto.

[dougsland]

CI/CD failing with the agent-flood test which is related to #416

[dougsland]

/hold still executing a bunch of tests.

Okay, the patch works in ostree and also regular images:
