Support for single MachineConfig and Ignition files

[pbertera]

I find myself many times working on MachineConfig files or Ignition files extracted directly from the cluster of the MachineServer, without a full must-gather.
For that reason I created a script where 99% of the code comes from this project.

@kxr If you like the idea I'll work on a PR to have omg working on MC files directly without requiring a must-gather bundle.

@pbertera yes, I agree, I do that too and I am convinced that feature should be there. I already have coded the poc for this. I am currently working on some code restructuring (with this feature in mind) and hopefully this will land soon.

#45 is also requesting the same feature (requester used configmap as typo, they actually mean machine confing)

[pbertera]

Great!, please let me know if I can help with that
