   Since it should handle multiple *_section.

   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.

   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.

  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)

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

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

   This was missing when creating payment.

   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 is needed after slapos@1888c1f2

Without this, we can have such errors:
RuntimeError: Unknown ldd line ldd: warning: you do not have execution permission for `/opt/slapgrid/shared/bzip2/449734bcc91bae01810a28d0af447a66/lib/libbz2.so' for /opt/slapgrid/shared/bzip2/449734bcc91bae01810a28d0af447a66/lib/libbz2.so.

Indeed, the permission for the lib itself is:

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

It should be an action on an instance node

See merge request !607

This is mainly about error handling, simpler and more useful.

- Always warn when a valid SR can't be loaded, with a message that
  contains the original exception (for example, compared to before
  this commit, it will tell if a JSON file can't be found,
  or where JSON has syntax errors).

- Same as previous point if serialisation type is invalid or missing.
  If the caller needs it to transform parameters (parameters file),
  it will raise with the original exception. Otherwise, it falls back
  on json-in-xml. In some places, such fallback is a change of
  behaviour and I have no opinion about it except that at least
  it's now consistent throughout slapos.core.

- Remove warning about RootSoftwareInstance/default: meaningless
  because contradicted the comment, and useless because the transition
  to 'default' is already complete for SR schemas. There are still 3
  lines of backward compatibility code for the rest of slapos.core.

- Don't read the same file several times. Note however that this
  performance fix is only for the SoftwareReleaseSchema class:
  the caller should be fixed to not instanciate several times with
  the same parameters (from do_request & _requestComputerPartition).
