This was introduced in 081e745e and I don't see how it could have been
useful.

    It was used on OrderBuilder_generateUnrelatedInvoiceList but the code dont relies on it anymore.

  Most liketly a copy and paste mistake

    Whenever you define a slave, the option_index inst the software-type but the property of the dict/object.

  This category is used whenever the user wants disallow allocation for the time been. It do not intend to re-open again after a procedure or do not intend to terminate the machine, just dont want anything be allocated on it.

   category close and not closed, and do not auto cancel upgrades for computers for termination.

   This should be handled by setting never on upgrade scope.

   Those actions were dropped from ancient site and forgotten to be removed.

   Only Monitor Scope should be taken into account.

   Whenever allocation scope changes, the capacity is close, and the proper alarm will re-open it later a moment after. This prevents when you change from close to open, to get a miss-updated window, and something is allocated before it capacity is calculated.

     Do not touch on monitor scope, except when it is None or allocation is "Close Forever", this allow the user to keep monitoring closed computers (Maintenance, termination...), since ONLY allocation is closed, and the computer is supposed to work normally with whatever is inside.

  ... to decide which computers to select for check for upgrades

It's very useful in some deployments to control maximum time of
partition processing. This parmater can end up in slapos.cfg configuration
file or command line.
