follow changes done on upstream for erp5 code.

  Use from slapos.util and convert str to bytes (as expected on python3)

   Probably this was based on some outdated version, since the calculation already changed on:

       erp5@6ded2571

  This solves a lot of warnings in python3

No need to fetch all parameters if not accessed.
This will speed up the recipe.request.

No need to access invalidated instances.

Also try to reduce conflict, and try to not block indexation activities.

 - fix the test failure introduced recently
 - fix grammar
 - log the software URL without ... at the end, so that we can click
   the link or copy it more easily

No need to install all officejs bt5.

This increase complexity, as user do not get the impacts of such changes.
Better create a new remote node if needed.

  For now the system allows allocate with instance_guid on remote, so it is not good
  to check

The performance impact is way to important, as it requires to
fetch all schema files.
For history, one use case was: 10 seconds to validate, 50ms to request.

Software releases should instead use the slapconfiguration:jsonschema
recipe to reject wrong input.
The recipe must use the schema informations stored on the installation directory.
slapos!1638

Move automated schema validation to the cli/request.py client.
Inform when the client start the parameter validation, to spot slowness.

No need to call everytime slapos node instance runs (every minute)

   rely on portal_template API to compareVersions

   Create a ticket if the SlapOS version into the monitored compute node is lower them minimal supported version found for the current master.

  If you access the listbox before the subscription request is indexed the link is broken on the listbox.
