- configurations like form definitions are saved as objects into data-storage.metadata to allow jio.get

- this prevents the appcache-local storage sync to store unnecessary resources like gadgets

- hardcoded JSON was removed
- form definition is get from jio storage (erp5 for now)
- rendering is done in controller.js using form definition and context (jio document)

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

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)
