Purpose of this commit is to allow moderation on incoming messages in
discussion channels. On some channels on which moderation is required
messages should be in a pending moderation stage. Moderators can accept
or refuse messages as well as always allow or ban messages coming from
a given set of emails.
Channels now have an option to be moderated. Moderators can be added on
channels. They have access to a specific UI in Discuss to see and take
action on messages waiting for moderation.
Concerning mail.thread message that are pending moderation are not notified.
It means nobody receives a notification about them. Moderation process calls
the notification once the message is validated.

This commit is linked to task ID 29521. Closes#21921.
There is a test checking message access rights and search results. It
searches for messages created in the test class having a subject like
Test. However this search may return more results than expected. For
example project create messages containing Test. As we want to keep tests
independent let us rename the test data to ensure everything works as
intended.
