Look for unprocessed Data Array periodically.

The comparison script generate the difference between a server node's
array and the reference database's array. It iterates over several
database types.

The transformation script transforms a Data Stream (raw data) into a
Data Array (integer array). It uses the mixin to map each file path with
each file's hash.

The mixin provides an interface with two reciprocal mapping dictionaries.

Alarm_handleAnalysis.py is a Wendelin script.
The scripts added here create the ERP5 objects necessary to handle an
incoming scan as raw data.

PathTemplateItem: Add ingestion policy.
SkinTemplateItem:
- Add easier object creation from Data Product (Data Supply and Data
  Transformation).
- Add script to get required parameters.

currently in "add ingestion policy" but may be a separate commit?
the files here are modified later (rather than being in their current
state from the beginning)

Add categories label scans according to their type (reference scan,
from a server node, etc.)
Exclude additional categories from Wendelin. This is required for the
slapos.core tests to pass.

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.

   Reduce the number of scripts and refactor the query script to rely on getMovementHistory.

   Before only the latest event was notified, to reduce the list and only to ping the user to access the site. Now all events are considered on the list (not the latest ones) and include some general clean up on base RSS feeds.

  Now the goal is save the configuration and later assert with saved configuration on the actual site.

  This may give us other uses for this tooling, like, save before and after an upgrade (to know the actual delta) and save after an upgrade to know later the local changes done over time.

  This without loose the possibility of audit (since you can upload a file after fetch the configuration from the unit tests)

   We shouldn't keep this in git, but it should be created or handled after an upgrade by the developer.

   Events are creates via script (and API) now, instead jio_post.

Add `README.md` instructions explaining how to adapt the migration
tests after upgrading the proxy database version.

When migrating entries, use `INSERT OR REPLACE` to get rid of duplicate
rows that cause constraint violations, instead of raising an exception.

Note that this only affects the `forwarded_partition_request` table:
for other tables it changes nothing in terms of behavior because the
intial tables already cannot contain conflicting rows.

Insert duplicate entries in `forwarded_partition_request` table of each
database dump of previous versions, and assert that only a single entry
remains after the migration.
