[ADD] mail_tracking_mass_mailing

==============================
Mail tracking for mass mailing
==============================

Links mail statistics objects with mail tracking objects.

Installation
============

This addon will be automatically installed when 'mail_tracking' and
'mass_mailing' are both installed

Usage
=====

From mail statistic object, you can see:
- Email tracking state
- Email related tracking object
- Email related tracking events

From mass mailing contact, you can see:
- Email score, in order to clean up your lists from bad score emails

As a bonus feature, you have a new checkbox 'Avoid resend' in mass mailing,
in order to not send twice the same email to the same recipient. This is very
useful when you want to resend the mass mailing after changing selection
recipients. Notice that recipient selection could be a domain over a model, so
result ids could change over the time. With this flag you can send
the same email several times but only once to each recipient.

Testing this addon failed if i.e. `mass_mailing_list_dynamic` was installed before.

Moving tests to post-install mode fixes integration tests.

* Change references to mail_mail_statistics model with mail_trace
* Change references to mail.mass_mailing model with mailing.mailing
* Change reference to statistics_ids field with mailing_trace_ids
* Change reference to send_mail method with action_send_mail
* Replace mailing.mailing name for required subject field
* fix view reference not_blacklisted with filter_not_email_bl
* fix not-stored compute, set value for all the records

If an exception is caught by ir.mail_server.send_email in mail_tracking module,
the mail.tracking.email record will appear in error but the related mailing
trace would still appear as sent because mail.mail._postprocess_sent_message is
called without any failure_type in mail.mail._send in the mail module (as Exception
is not raised after being caught in mail_tracking module).

Since _postprocess_sent_message method not only sets the mailing.trace state in
mass_mailing module but can also delete the mail.mail records in mail module,
we need to ensure the mailing.trace is written accordingly to the tracking here,
and avoid having the mass_mailing module set a 'sent' status if we had an exception,
hence the usage of a context key to ignore possible writes.
