The check node status alarm needs to know what Data Array is to be processed.
Draft: Initial state.
Converting: the Data Array is currently filled by the transformation script.
Converted: ready to be processed.
Processed: already processed.

The categories are used to determine the source of the data.
The data comes from a server node or a reference image.
The data comes from a particular distribution too.

because json output is different on python2 and python3 and cli is only
used on python2, we don't test the exact output in python2.

This is particularly needed for old OS with python2: very old versions of
pip are trying to install latest version of eggs no matter their python2
compatibility whereas pip 20 is making sure to install only python2
compatible eggs.

   Revert inclusion Base_getNodeTitleAndDate and use checked_permission to only get title if the user is allowed to see the document.

   Author is optional so keep empty isn't a problem.

See merge request nexedi/slapos.core!434

Until now, the broadcast address was used for the tun interface instead
of the first address of the range.

  We do want to ignore payments that occur after the at_date.

  We want to know if at a certain date, there still unpayed documents older them that date, if the document is payed after, (and grouped) we unconsider it.

   This was missing to remove since we dropped all mass upgrade code and relies exclusively on Upgrade Decisions.

   Upgrade decisions are also tickets (messages are issued), this makes things consistent with the other tickets (Regularisation Requests and Support Requests)

   This allows administrator see issued messages.

   node_title is another person/organisation title, which was raising if an administrator use himself as sender on the event.

See merge request nexedi/slapos.core!431

If computer partition requested state is `started`, slapos node boot will start
partition services on reboot, event if the node is not able to connect to master or
has no internet.

   ... Unify scripts into Base_getEventList

  In order to use getMovementHistoryList too

   It is used to get the events that follow up to a ticket that aggregates (or sub object aggregates) to an document (usually Compute Node or Instance Tree).

   Reuse Base_getOpenRelatedTicketList to query tickets consistently and extends original goal to also show Upgrade Decisions.

   This tab shows all Tickets related to the computer and to all instance trees that has one instance allocated on it (even if isn't the one that is failing).

   Use default_or_child_aggregate_uid is enough (and simpler).
   Use specific states to be consistent with RSS queries.
