Add filter to disable email sent by wp-admin/network/site-new.php

Related: #42134

wp-admin/network/site-new.php contains a call to wp_mail() which sends an email when a new site is created from Network Admin -> Sites -> Add New on Multisite. (Ref).

It's not possible to disable the email via a filter. One should be implemented similarly to the send_password_change_email filter. (Ref).

Instead of adding a filter for disabling these emails, we could put the code that is responsible for sending the email into a new function and call that function using a hook. This has been done in #33587 for comment notifications and also for signup notification emails in multisite.

Add new function with hook - wpmu_new_site_notification - unify usability with wpmu_welcome_notification

[dharmin16]

added the feature simmilar to wp_welcome_message(). E.g. Filter 'wpmu_admin_notification' to disable or bypass. Filter 'update_admin_notification' and 'update_admin_notification_subject'} to modify the content and subject line of the notification email.

This ticket has not received any attention during the 5.2 cycle. With beta

Refresh the patch and clean up some code

Hi,

In 42135.4.diff, I refreshed the last patches and I edited up some function names and code.
I tested this code locally and it seems to work, but it will definitely needs a deep review.

Cheers,
Jb

This still needs some work. With 5.3 beta 1 in a few hours, it needs to be punted.

I'm closing this as a duplicate of #42134 because the functionality overlaps a lot and this will keep the discussion and patches in one place.
