feat: commission machines in New state by their PXC MAC

[skatsaounis]

Fixes: #151

[sempervictus]

If we kick commissioning from tf, i think that we should be able to assign commissioning and test scripts such that machines are qualified for function and consistency - otherwise workflows gated by component qualification don't work requiring humans to recommission again after this seemingly enforced commissioning pass that doesn't actually "check the boxes" for QA.

Secondly, how does this work with manual power or temporarily inaccessible ready-state hosts? This seems to "take action on behalf of the user" vs being a state of resource induced by the user or a separate resource type entirely (ready, commissioned, deployed, broken, etc being either states of a resource or entire resources themselves)
