[erp5_web_monitoring] Fix concurence problem on destroy OPML while sync is running or start just after

If Sync start in background and destroy OPML is launched, some data can be removed while sync is writing. So we prevent sync to run if destroy OPML is running and also, we refuse to destroy OPML if sync is running.

If the search result is only one item, redirect to the item view page, else redirect to the list of that items and let user choose the good one.

Monitor Jio storage has been updated to fix monitoring global Json files and set correct portal_type to it. The fix allow to keep backward compatibility with old/non updated monitoring backend instance.

erp5_real_time_inventory_accounting: Accounting Transaction state should be 'Posted to General Ledger' (stopped), not draft.

Such as:
  - getStartTransitionDateList() and getStartTransitionDate().
  - getDeliverTransitionDateList() and getDeliveryTransitionDate().
  - ...

Where the non-List accessors returned the last element.

Use Case: Set AT.{start,stop}_date from PPL stop transition date.

Until this commit, loading a ZODB Component would add it to the current Request
object to prevent its reference counter reaching 0 (thus its global being reset to
None and then being later GC'ed) when a reset happens in another Request.

This problem was found when investigating testFunctionalConfigurator failure
when installing bt5s as requested by the Configurator:
  1. Request R1 calls Zuite_waitForActivities importing extension.erp5.ERP5Zuite (M1).
     => Add M1 to R1._module_cache_set.
     => M1 ref counter equals to 2 (sys.modules and R1._module_cache_set references).
  2. R1 terminates and is GC'ed.
     => M1 ref counter equals to 1 (sys.modules).
  3. Request R2 runs Configurator configuring the Site.
  4. testFunctionalConfigurator calls Zuite_waitForActivities to wait for the
     Configurator to finish (request R3 which may take ~15 minutes). This calls
     time.sleep() in a loop where 'time' module is imported at top-level.
  5. R2 installs bt5 triggering reset.
     => M1 ref counter equals to 0.
        ===> M1 global variables are reset to None and thus 'time' is set to None
             raising an Exception in the next call of time.sleep() in the loop.

The easiest way would be to have a hook on sys.modules dict lookup and thus add M1
to R2._module_cache_set when being imported, but this is not supported... Instead
create a global cache on erp5.component package.

This test alone does not define site-dependent security groups, so this
change is not required as such.
But in real configuration, ERP5 instance define security groups, which
sometimes (often ?) depend on which site a document or user is linked to.
When multiple groups apply (ex: having a certain function at a certain
site), the final group is composed by joining group identifiers using
underscores. This forbids using underscores in group identifiers.
And group identifiers are generated from document's (here, the Category)
codification if set, otherwise the reference if set, otherwise the document
identifier.
So set a underscore-less codification on these categories so this test can
be run on tests where security is configured to include site in security
groups.

as the comment (which is removed now) said:

```
        XXX: This method is broken, since "total_size" field is not
        present in the listbox rendering any longer. It should be
        removed.
```

Also:
- make sure that Listbox always knows how many lines are to be displayed.
- add testPagerWithCustomListMethod in listbox_zuite of erp5_ui_test,
which checks that listbox jumping to previous/next/first/last works correctly
for a list method that returns only the elements that the listbox is to render.

set.__iadd__ does not like non-set values, but the intent of this API is
to allow just any iterable (producing strings) to be returned, so use
the more tolerant set.update method instead.

This is a mix of features to help time tracking and reporting with small unrelated bug fixes and improvements.

To help time tracking we show the time on support request with hour:minutes everywhere and set a stop date automatically. We also add interaction so that "user doing" is automatically added to the support request so that we can see "who did" and make reports based on this.

Bug fixes/unrelated features:
 * when project does not have supply lines, show all services members of the support request use. Also change to pass relative URL of services, usually we don't pass IDs, but relative URLs. This is a visible/breaking change, because it's now required to configure services use. Because it's also required in erp5_crm, I expect it would not break too much. 
 * momentjs' related time was not refreshed, so they kept displaying "a few second ago" even hours later
 * don't set HTML source as post title
 * prevent double submit of comments in support request app.
