erp5_trade_ja: New bt5 for wkhtmltopdf printout for 'Sale Invoice' with >2019/10/01 new Japanese VAT ratio support.

Based on the following ODT Templates (erp5_invoicing):
  * Invoice_viewAsODT.oot.
  * Invoice_viewAsODTStyles_l10n_ja.oot.

wkhtmltopdf template is based on work from slapos_accounting bt5:
  * SaleInvoiceTransaction_viewSlapOSPrintout.zpt.
  * SaleInvoiceTransaction_getSlapOSPrintout.css.zpt.

Conversion Server code is no longer bound to OOo, as emphasized by:
  * Renaming of Preference Properties ooodoc_server* to document_conversion_server*.
  * Conversion Server exceptions are already defined in Document.py.
  * Conversion Server also handles video/audio/... conversions.

Thus, refactor the code to connect to Conversion Server by moving it from
Products.ERP5OOo.Document to Products.ERP5.Document.Document (while keeping
backward compatibility):
  * Renamed:
    + OOoServerProxy => DocumentConversionServerProxy
    + OOO_SERVER_PROXY_TIMEOUT => DOCUMENT_CONVERSION_SERVER_PROXY_TIMEOUT
    + OOO_SERVER_RETRY => DOCUMENT_CONVERSION_SERVER_RETRY
  * Moved:
    + enc
    + dec
    + global_server_proxy_uri_failure_time

Also, Introduced erp5.module.TransformLib (in erp5_core as currently all Transforms
are there even though it should probably not be so) to define DocumentConversionServerTransform
and which will hold libtransforms content when this will be moved to ZODB Components.

Note: Ideally, OOOdCommandTransform should inherit from DocumentConversionServerTransform
but wkhtmltopdf Handler on Cloudooo side is a hack only implemented in Manager.convertFile()
whereas OOOdCommandTransform still uses legacy Manager.run_generate(), so leave it as it is
to avoid breaking things (this will be addressed in a separate MR).

ZODB Components: Add 'Origin' (source_reference) field showing from which FS module it was imported.

* pylint may return a false positive error which have to be disabled and
  failing to import it because of that requires to edit on the FS and try
  again so it is not practical for a whole Product. Instead it is easier
  to import it and not validate
* Validation was done only for 'Test Component' and 'Extension Component',
  but all imported Components had their consistency and source code checked
  and this is not consistent to not validate but do these checks.
* importFromFilesystem() was checking consistency and source code, and this
  was done again when validating.

So leave the imported ZODB Components as draft and let the developer fixes
issues upon validation before committing.

ZODB Components: List of migratable 'Module Components' in Products.XXX.* should include any kind of objects and not only modules.

This fixes Products.ERP5VCS.Git module not being displayed because
Products.ERP5VCS.__init__ only imports one of its class and not the whole
module (and the module was not imported anywhere else too) so it was not in
Products.ERP5VCS.__dict__.

useStdin=False => temporary file was not created.
useStdin=True  => temporary file was created.

When multiple repositories exists and two of them contain scalability_test package be wiser and really check if neeeded Test Suite class exists before trying to load it.

When running tests the path to git command is just git, because we have
set $PATH

updateConfiguration is a method to set the list of partitions, not to
add partitions to an existing computer. The previous (slapos.core
<1.5.0) implementation of slap proxy was incorrect and was adding more
partitions each time it was called, but that was never the indented
behavior.

Prepare the list of partitions and call updateConfiguration only once to
set all partitions.

This should fix SLAPOS-SR-TEST that are still using erp5.util

Some tests where patching SlapOSControler to replace methods by a no-op,
but this was never reset. I believe we should rewrite this using mock
which takes care of un-doing the patches for us and makes this testing
easier, but for now I'm just reseting the missing methods like all
others were already reseted.

configparser read options as strings, node_quantity is not supposed to
be an int.

pkg_resources.resource_string reads the file as binary, if we want to
substitute in this string we need to decode it.

ZODB Components: Monkey patch pylint to avoid 'No config file found, using default configuration' on stderr.

Another solution could have been to have a configuration file for pylint instead
of command line arguments but it depends on the type of Component (for example
'Interface Component' has specific arguments).

Value of text_content is an unicode string whose (inside XML) encoding is utf-8. This inconsistency raises in xml library thus it is safer to convert back to utf-8 which is the intended encoding anyway.

After upgrading bt5s, portal_sms may still ERP5BaseBroken until restarting Zope.

ZODB Components: Allow migration of {Interface,Mixin,Module,Tool} from Business Template UI and on all Products (not only Products.ERP5).

This introduces the following new ZODB Components:
  + Module Component: Non-Documents/non-persistent classes of modules usually
    found at the top-level of Products (eg Products.ERP5.XXX) on FS. Considering
    that all other Components types are actually Modules, make it the base class.
  + Tool Component: Tool directory of Products on FS (eg Products.ERP5.Tool.XXX).
    => DiffTool and CallableTool are now 'Tool Component' instead of plain
       'Document Component' and properly registered as Tools like FS Products Tool.

Skip CMFActivity and HBTreeFolder2 Products for now in migration View for now as
almost many Portal Type classes have ActiveObject or HBTreeFolder2 in their MRO
and these Products will be done at the end anyway...

This often divides the size by ~3,
and also memory usage if it is loaded again.

* Add erp5_core_proxy_field_legacy to dependencies (because of (at least) my_password).
* Rename ERP5ShortMessage.Errors module because the name is too generic for a 'Module Component'.
* Fix type_class of SMSTool: This should be the name of the class only, excluding the module.
* Add missing __init__.py to tests directory so that it can be migrated.

This is done by inheriting most of the code of ConflictFreeLog,
i.e. using a doubly-linked list:
- for fast iteration of the first elements, and in particular
  immediate access to the first element (used for creation date);
- that keeps track of the history length;
- that implement fast reverse iteration (although it could
  have been done without changing the data structure).

The size of buckets is not fixed anymore to 16 items:
like ConflictFreeLog, WorkflowHistoryList is also a good candidate
to look at the estimated serialized size of the bucket in order to
decide if elements should be added to a new one or not.
Then developers won't have to care about using Pdata or not.

The size is bigger than the ConflictFreeLog default,
because workflow items look a lot alike and adding
a few more is cheap when the ZODB compresses.

No more optimized __getstate__ (except for workflow histories that
have not been migrated) so BT export will be a bit more verbose.

The BBB code is because of
