Rely on getAccessStatus Instead

   This introduce API for request support and add events on Support Requests

   This creates a Support Request

    In case the instance isn't linked to the tree properly (due Garbage Collect unlinked it), stop the instance directly anyway.

   This API replaces the usage of SlapTool code for handling data stored in memcached. It introduces an New API for it at the context of the objects to handle volatile data used on SlapOS context.

This reverts commit 2d50c8b8.

We are not ready for this, for example on debian 10 perl link with
libnsl.

For reference, one example test failure:
  https://erp5js.nexedi.net/#/test_result_module/20220111-190A520F2/20

We'll try to re-apply this later once no software use system libnsl

Since slapos commit 246be932e (component/libtirpc,libnsl: initial
inclusion, 2021-12-28) we have a slapos component, so no reason to
accept the system library

logrotate stack uses srv/backup/logrotate

This MR aims to introduce and extend the internal API with the support for manage:

   - Project
   - Organisation
   - Site (also Organisation)
   - Tokens
   - Computer Network
   
So via the introductions of workflows we included the following methods:

  - Project.approveRegistration()
  - Project.leaveProject()
  - Project.acceptInvitation()
  - Organisation.approveRegistration()
  - Organisation.leaveOrganisation()
  - Organisation.acceptInvitation()
  - Person.requestProject(project_title)
  - Person.requestOrganisation(organisation_title)
  - Person.requestSite(organisation_title)
  - Person.requestToken(request_url)
  - Person.requestNetwork(network_title)
  - ComputeNote.requestTransfer(...)
  - InstanceTree.requestTransfer(...) 
  - ComputerNetwork.approveRegistration()
  - ComputerNetwork.requestTransfer(...)
 
  
This API with minor exceptions, don't replaces the way the Hateoas/JIO website interacts with ERP5, so the original scripts are kept and just changed to call internal APIs.


See merge request nexedi/slapos.core!348

   Drop code that is never called anyway.

  This makes easy write or update tests per workflow-basis

    Drop an duplication, probably came from copy and paste

   Introduce API on person to handle the requests of Organisations and
Sites.

   This aims to transform *_createMovement into an proper API to handle location/project/owners transfers between Sites/Project/Organisations.
