This commit aims at unifying the UBL formats for invoices and credit notes.
Starting from the work of LAS, the module account_edi_ubl_cii contains the templates for UBL and CII,
and provides inheritance for UBL: UBL 2.0 < UBL 2.1 < UBL Bis 3.
It contains also the formats E-FFF, EHF3 (fully covered by Bis 3), NLCIUS, XRechnung (in UBL), Factur-x (the only one in CII).
All these formats are also improved to pass the ecosio validator and/or the country specific validator
(for Factur-x: the validator from the FNFE, and Chorus Pro).
Note that the xml files generated contain the pdf of the invoice/credit note encoded in base64.
An xml file alone imported in Odoo will thus automatically retrieve the pdf.
Before generating the xml files, we now also check a series of known constraints and possibly display
a warning on top of the move view if some are not enforced (the xml file is generated anyway but it might not be valid).
Tests were required: a new module was needed with dependency to the tested l10n: l10n_account_edi_ubl_cii_tests.
The prefix "l10n_" prevents runbot from launching the tests everytime.
The following modules are removed:
* account_edi_facturx
* account_edi_ubl
* account_edi_ubl_bis3
* l10n_no_edi
* l10n_nl_edi
* l10n_be_edi
