Use same spreadsheet for all consulting configurator tests

When there's only one quantity unit in the group a conversion group, one
definition is needed (this might be a bug).

Instead of using a spreadsheet for categories, use
erp5_configurator_standard_categories business template.

This business template also configures quantity unit definition in the
new way and no longer use obsolete way of setting quantity property on
quantity unit categories.

The included spreadsheet is still used, but all categories except group and
site have been removed, it now only contain group/my_group and site/main.

Some configurator profiles uses a spreadsheet to define categories
(consulting configurator), some use a business templates.

For the ones using business template, because the categories are not available
yet we have the values directly in the script.

from erp5_configurator_standard/standard_category.ods

from erp5_configurator_standard/standard_category.ods

trade/order trade/discount and trade/tax were only in
erp5_configurator_standard/standard_category.ods

It seems that with ${here/portal_url} returns the ERP5 url , for example http://nohost/erp5 instead of

http://nohost/erp5/web_site_module/renderjs_runner/

Since a89afa43 (Formulator: Support disabled items in all ItemWidget subclasses., 2014-04-02) we can include disabled items in listfields.
This was used for example in erp5_crm to show the services with their hierarchy as disabled items and was useful to display the hierarchy.

In some fields, we don't want user to select "nodes" categories, but only select "leaves" categories (ie. select the most precise category).
This always had a problem when using "Indented title" as display method for categories, because the user can not see the actual hierarchy. This is about making it possible to display hierarchy of categories in this case where we select only leaves, so that it displays like this:

![screenshot of a category with disabled items for hierarchy](/uploads/0f3e8ef68ab6e2ec424e4e8d42fc5e2a/image.png)

This required to:

 - introduce a new category API, `disable_node`, which is semantically very close to `filter_node` except that instead of filtering out node categories that are kept with `None` as related URL. Symmetrically, we also introduce `disable_leave`
 - make `ParallelListField` support disabled items. Even if this was properly supported in underlying fields, some parts in `ParallelListField` did not differentiate between `None` and `''`.
 - modify several forms to use `disable_node` instead of `filter_node`

See merge request nexedi/erp5!1199

For PDM/Trade we use:
 - "Site" for node category
 - "Warehouse" for node
 - "Owner" for section category
 - "Owner" for section

For Invoicing/Accounting this does not change.

Also, since in PDM/Trade context we are sometimes only taking care of physical movements/quantities and not the ownership, make sure that:
 - "Site" is first in report dialogs
 - "Section Category" is not initialised from preference, so that reports show the quantities in a location regardless of the ownership

See merge request nexedi/erp5!1202

- add an empty item to the list, so that user have to choose something. The empty item was missing here:

![image](/uploads/5be3e9d5acf1233270516c7463dbfdd4/image.png)

If there's an empty item and we force user to choose, there will not be the problem that user can forget to select the good value and mistakenly generates for the Fifo because it's the first value.

- translate values

A few small fixes to form and page templates to allow their translations

Also, as OAuthTool class is only used as a Folder ({Google,Facebook}Connector) remove
{unused,unmaintained,unfinished} code:
  * Properties are statically set on portal_oauth directly with non-persistent classes
    define in OAuthTool.py. This prevents migration to ZODB Components as migrating
    OAuthTool.py to erp5_oauth would break upgrade: chicken & egg issue: we need these
    classes on importFile(portal_oauth.xml) (portal_templates.download()) but they are
    not available until the bt5 is installed....
  * Several properties are supposed to be secret but statically set in OAuthTool.py.
  * This code has never been used since its introduction 9 years ago.

Unlike trade and like accounting, for invoice we are using "Section Category"
term for section category, it's no longer about "who is the owner of this
stock" like in trade, but already "who is the entity" like in accounting

 - add an empty item to the list, so that user have to choose something
 - translate values

for consistency with other stock reports such as
Base_viewStockReportBySiteDialog

most trade and PDM report are about "what quantity of resources do we
have here", in most uses cases, we are not concerned about who is the
owner of these, so it's probably better to not select these by default.

This tab was probably useless, let's remove it.

This also make use consistent for all resource types, the filter_node was only
effective on service, now it won't be possible to select nodes on any resource.

So that user can see the hierarchy (especially when categories are configured
as indented items) but not select nodes

instead of the deprecated Resource_viewFieldLibrary

by using disable_node instead of filter_node, we can keep the hierarchy and
this is much more understandable when using indented titles for categories

It does not seem easily feasible to implement support at this level. If support
is needed, I guess the best would be to make a custom hash script that generate
the full category item list again, then it would know in which subfield list to
"dispatch" the None items.

value of None is diferent from '', '' is the empty value when nothing is
selected, but None is a disabled item
