- hateoas script only returns the form definition
- the form rendering is done in the JS side (controller gadget)

- it still returns a hardcoded rendered json form until JS side (controller) does the rendering

- controller gadget temporarily uses jio_storage to get html-post form
- controller gadget uses -for test- a manually request to hateoas script
- some code cleanup in hateoas script and still a hardcoded form definition for html post only

Notify the user and redirect to the storage page to force user to enter credentials if needed

 * Review SMS sending API to move the complexity and the various parameters from the interface script `ShortMessage_send` to the gateway interfaces.
 * Fix problem with mobyt with messages longer than 140 characters
 * Fix [#20170709-17309B6](https://nexedi.erp5.net/bug_module/20170709-17309B6)

This introduces a new portal type group "payment request"

This fixes the issue that a transaction with many big messages failed to
commit. By dynamically find the maximum allowed size of a query, it also
speeds up insertion by minimizing the number of queries.

e84d2b51 introduced template_{interface,mixin}_id BusinessTemplate properties
in erp5_property_sheets without keeping backward compatibility and thus
preventing update:
  Module Products.ERP5.Tool.TemplateTool, line 1446, in upgradeSite
    update_catalog=update_catalog)
  Module Products.ERP5.Tool.TemplateTool, line 1289, in updateBusinessTemplateFromUrl
    imported_bt5 = self.download(url = download_url, id = id)
  Module Products.ERP5.Tool.TemplateTool, line 382, in download
    bt = self._download_local(path, id)
  Module Products.ERP5.Tool.TemplateTool, line 328, in _download_local
    bt.importFile(path)
  Module Products.ERP5.Document.BusinessTemplate, line 5887, in importFile
    self.storeTemplateItemData()
  Module Products.ERP5.Document.BusinessTemplate, line 5165, in storeTemplateItemData
    InterfaceTemplateItem(self.getTemplateInterfaceIdList())
AttributeError: getTemplateInterfaceIdList

ZODB Components: Likewise Document, add Mixin (erp5.component.mixin) and Interface (erp5.component.interface).

* One Mixin/Interface class per ZODB Component.
  => Already the case for FS Mixin, not for Interfaces.
* ZODB Components module name ('reference' property) and class name:
  + Mixin: FooMixin.
  + Interface: IFoo.

Rationale:
  + Avoid current FS hacks: registry (Mixins, mixin_class_registry) or import
    all classes explicitly in __init__.py (Products.ERP5Type.interfaces).
  + Consistent naming.
  + Consistent with ZODB Documents Components.

Also, modify pylint checker to handle Zope Interfaces:
  + E: 4, 0: Inheriting 'Interface', which is not a class. (inherit-non-class)
  + E: 5, 2: Method has no argument (no-method-argument)

It seems developpers didn't update their instances.

The fields are displayed only if some portal types are configured as
member of payment_request group. This means that currently it's not
displayed by default.
