- 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)
 * add an (incomplete) test

This introduces a new portal type group "payment request"

/reviewed-on nexedi/erp5!831

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.

This moves the remaining DTML queries to Python, dropping the 'activity' skin.

Dealing with conflicts of uids is easier if the inserted uids are consecutive:
now, only 1 random value is generated, as base uid. This also preserves the
order of insertion, which is wanted for performance reasons:
- No more random write in the primary index.
- When modifying several lines of several documents, 1 document being processed
  at a time, we'd like that any grouped activity (usually indexation) follows
  the same order, so that a processing node prefer many lines from a few
  documents instead of mixing lines from too many documents at the same time.
  This is usually better for caches.
