Add machine status info about import/migration event

[aschiavo]

Change Summary

What and Why:
This change notifies the user when a machine was created by flyd because of a migration action.
It's a first iteration while a better solution is implemented in nomad-firecracker.

What would be the example output? If possible, I'd like to use migration/migrated instead of import.

@kzys This is the output for the command:

 go run . m status -a aschiavo-epic-stack-691c

Sounds good to me to change to migration/migrated , I went with import for consistency with flyd isImport but from user perspective is probably clearer if we go with something migration-related .
Do you have a preference for either migration or migrated? I'll make the change tomorrow morning

[kzys]

Yeah. import is our internal lingo. Personally I like migrated=true

[aschiavo]

Done!
