PURPOSE
Global purpose is to rename some methods and add some docstrings to clean
API of notification methods used in mail thread. Notably use _notify_thread
prefix for main methods, and _notify_by_'mean' for tool sub-methods.
SPECIFICATIONS
Remove unused arguments coming from old implementation and usage. They were
introduced notably for performance reason when cache was more often invalidated
which is not the case anymore. Anyway when parameters are unused it is always
better to remove them.
Remove ``notify_by_email`` parameter in ``_notify_thread``. It is only used
in channels to avoid notifying people of some automated notifications. The
same behavior has been cleanly implemented at odoo/odoo@018820d .
Rename methods, starting with ``_notify(_records)`` to ease their grouping
and understanding. Add some additional prefixes like ``_notify_by_'mean'``
and ``_notify_get_recipients`` for recipients related computation. Add some
docstrings, notably when parameters usage is not clear.
Some linting is also performed in updated actions, just to lessen styling
issues notably on runbot.
This commit should not change anything functionally as it contains only
some renaming and docstrings updates as well as some outdated parameters
removal.
