[IMP] payment, website_sale: better control of sale order confirmation in ecommerce.

Auto confirmation is now controlled by a field on the acquirer
that proposes to confirm
- at payment (Pay Now button on ecommerce)
- at payment confirmation (transaction feedback)
- never

Also fixed the state of tx for transfer transactions that was modified
for debugging in a previous task but not reverted.
[IMP] Removed crm_profiling module & crm.payment.mode, crm.segmentation, crm.case.categ models and related code. Added new crm.phonecall.category, crm.lead.tag, crm.claim.category and crm.helpdesk.category in replacement of crm.case.categ. Remove default_section_id on res.users object and related code.
[IMP] replace section_id with team_id
