When you have different companies per Subscription Conditions

logging is configured globally in SlapOSApp.configure_logging and:
 - if logging to file is enabled, it is logged with maximum level
 - logging on the console depends on --quiet / --verbose command line flags

Default log level of this logger was DEBUG, which is just fine: the logger
emit all messages and the file/console handler decide to output them or not

Because we configure logger after Flask initialize its own logging, for
Flask >= 1.1.2, we remove Flask logger as described in
 https://flask.palletsprojects.com/en/1.1.x/logging/#removing-the-default-handler
Since this is internal API which doest not exist on old version of Flask, we
adjust requirements to require a recent version of Flask.

   Subscription request workflow uses simulation_state rather them validation one.

   What happens when user don't pay reservation.

     Since we use Caddy rather them apache by default, change the field to input a value on tests.

slapos_subscription_request: As dates are simetrical on Invoice and Payment, the value is not negative anymore

   This with price not zero is covered by another tests.

   Failures:

      portal_skins/slapos_subscription_request/SubscriptionRequest_checkRelatedAccounting:5:2:Dangerous default value {} as argument (dangerous-default-value)
      portal_skins/slapos_subscription_request/SubscriptionRequest_checkRelatedAccounting:15:2:Unused variable 'refund_service' (unused-variable)

   The input_movement_list weren't properly filtering causing grouping references been set with it's late occurency.

   It makes requests as non-subscription and for subscription cases, and assert if the invoice is correctly linked via simulation

  This is probably required multiple renames or upgrade project code base

  This fixes name convention tests:

     /portal_skins/slapos_crm_monitoring/SupportRequestModule_viewExportMonitorOPMLList
     'message': 'erp5-Guideline.Form.Report.Dialog.Is.Postfixed.With.Dialog: Dialog form name must follow ${portal_type}_view.*Dialog naming'

     /portal_skins/slapos_crm_monitoring/SupportRequestModule_viewInstanceMessageList
     'message': 'erp5-Guideline.Form.Report.Dialog.Is.Postfixed.With.Dialog: Dialog form name must follow ${portal_type}_view.*Dialog naming'

     portal_skins/slapos_crm_monitoring/SupportRequestModule_viewSupportRequestMonitorLinkList
       'message': 'erp5-Guideline.Report.Name.Uses.Portal.Type.Followed.By.View.Report.Name.And.Report: Report form name must follow ${portal_type}_view.*Report naming'

Because some programs did not have proper configuration for log files, they
were using automatically generated file names for log files. Correctly
define stdout_logfile configuration for all programs, used with
redirect_stderr=true, so that both stderr and stdout are in the same log
file.
