[MERGE] mail, hr_holidays, *: add out of office status

*: base, bus, mail_bot, test_mail

Before this task, it was not easy to tell when a user is not available (or is on holiday)
from conversations, such as from chat windows.

With this task, a user can now tell that he is out-of-office from the user menu preferences,
by defining an an out-of-office message. This information will be displayed to other users from
chat conversations and mention suggestions (i.e. with `@`).

Also, the computation of the user `im_status` has been changed when he has an active leave:
an out-of-office message can be set on the leave, and this will be displayed on conversations
instead of the user's out-of-office message from the user menu preferences.
