PURPOSE
Clean organization and models linked to Event Online feature introduced in
semi stable saas-13.3 at odoo/odoo@981f95bbf4 and odoo/enterprise@14722028ae
Also clean website event menu not being available in website event but only
in website event track, which implies some extra-code to manage it.
In short: merge website_event_online in website_event, website_event_track
_(online/session) in website_event_track.
RATIONALE
_online modules have been added to extend content of website_event and
website_event_track without having any impact on those module. First step
of cleaning is to move this content directly in base module.
track_session module is mainly a rewrite of track module. Second step of
cleaning is to move its content directly in website_event_track.
SPECIFICATIONS
Rename some Xml IDs to ease future maintenance of views, as event application
has a lot of sub modules adding their own fields inside base view of event
models.
