One minor comment inline under [rafael] tag. I had a comment previously
for the nodeGroupAdminOperation function which is not addressed.
[rafael] method_rc seems not to be set (to false) if the
AdminOperationInvoke fails without reaching timeout.
A general comment to big functions with break and continue is that the
flow is too complex to have a overview of. Consider refactoring in the
future.
