Display a blank page is disturbing in general, so at least show a loading bar with some message.

   The currency as parameter is useful for bootstrap region specific
    tests later on, and allow reuse this script to bootstrap dev environment
    in EUR or CNY to test payments.

   Entity is more accurate since it could be used on B2B context later.

  Make it reusable so that we can inspect the balance of the user for other purposes

slapos_accounting: Entity_getDepositBalanceAmount

  Remove non required code around the topic.

  Include checkInstanceAllocationWithDeposit on tests to checks the use case
    whenever the pay the deposit is required to allocate.

  Update tests to pay precise deposit, since a more accurate use case is
    check and pay a proper amount of deposit and check if the steps are
    working properly (ie.: Subscription request stays in submitted)

In some conditions there is no name attribute on tap, so allow real fallback
to interface name.

   If the instance empty dont display green but red, indicating something is wrong.

   Clean up and minimize the configuration a bit more, so it is easy to navigate.

   This allows, in case of error, verbose what to do

   Implementation changed, Subscription Request is a Ticket-like, so it goes to normal feed.

   If the Subscription Request still submitted, display it on ticket list, so the user has some information on what is going on.

   ... we dont require to create and use the user under the same transaction anymore.

   This was missing when creating payment.

that is part of gcc-10 and the system libquatmath can be linked if built with system gcc-10.

  This is long gone

   in addion to Software Product

  Remove some editable fields that were probably added due copy and paste.

This is needed after slapos@1888c1f2

Without this, we can have such errors:

Many old releases do not have such json, and must still be configurable for now

It should be an action on an instance node
