This contains changes for 2 points:
1. To improve view of ERP5 Catalog and its sub-objects .
2. Export Catalog Methods with no duplication between attributes and properties after migration.

These changes are pointed out  in comment here: nexedi/erp5!178 (comment 52224)

BusinessTemplate: Look for string type in property map while extracting Properties for CatalogTemplateMethodItem

After migration of ERP5 Catalog and sub-objects, the filter attributes are
now properties of Catalog Method(s). So, they are now already exported in
xml file for the method. Thus, no need to duplicate export in _catalog_keys file.

Also, installation should take care of the changes.

Also, add tests for them

[erp5_core]: No need to have export_properties action for ERP5 Catalog as we do cleanup of old manage_exportProperties function

According to guidelines, documents should have 'edit_workflow'.
https://www.erp5.com/documentation/developer/guideline/programming/erp5-Guideline.Programming.Naming.Conventions#never-forget-edit-workflow-on-documents

This follows the guidelines and also make it feasible to go to listbox
to search or make changes in sub-object list.

Also,
- Add 'More columns' in listbox for viewing Catalog Method list.
- Add title field in listbox view for Catalog content and Catalog Filter List
- Fixup links on these views which were not consistent.

- ERP5Site_getScalabilityTestMetric script gets metrics of last created objects
- Bootstrap script now creates the users for test

When accessing an ERP5 Site, we might have automatic migration of
tools. When this happens, we might not have yet access to scripts
like ERP5Type_asSecurityGroupId.

There was already try/except, so just move slightly more code
inside.

After ERP5-ification of catalog, its better to have Catalog Tool in action list
for ERP5.
