   Whenever an Instance Tree is destroyed (and archived), cancel the Subscription Request
   on Submitted state.

    This is required since the Submitted Subscription Requests count as required Deposit, and
    the user clearly didnt conclude his payment.

   Similar to "Pay" Section, it will display the outstanding amount right the way to pay. This allows the user "immediately" have their instance ready to allocate (validated) and it wont require to navigate to pay section or subscription request.

   This allows the script been used with normal user security roles,
   since only account_module is cause restrict access (by the current
   usage).

   destination section can be an organisation, so use shadow to avoid
   relax security.

   Display if the instance is payable (price currency/unit)
   Create and redirect to deposit payment if balance would require a deposit to the instance to work.

  This allows to to getPrice before actual create a subscription request.

In Suse SLE 15.6, ansible can be installed either from the OpenSuse
repo of from PackageHub.

The version installed from OpenSuse requires Python >= 3.10.
Thus, it depends on the modern Python (version 3.11) provided by the
Python 3 module, instead of on the Python provided by the base system
module (version 3.6).
Packages installed for the modern Python, such as pip, will have
python311 as a prefix instead of just Python.

On the other hand, the ansible version in PackageHub is older and
can be used with the older Python version.

Thus, we check if either version of the package is installed, and if
not we install the more modern from those available.

Previous messages were all showing relative URL of the object on which the script was executed.
This was likely a typo in the script and made messages unreadable. This commit restores proper behaviour.

   Probably it comes from a bad copy and paste, since it contains mostly payzen references.

   Create the documents on the fly on the tests, otherwise it may cause problems on production.

  We don't want mistakes when configure it.

  No reason to pre-configure test like this
