Allows users to send notifications to themselves (T306211). For sending
notifications to others, a new permission is created (echo-create),
assigned only to bots by default. For now, only one user can be notified
in one API request.
If the email flag is set in the API params, the notification is also
sent as an email, provided the user hasn't disabled email notifications
for the "api-triggered" category.
This feature is behind a feature flag. Set $wgEchoEnableApiEvents = true
to use.
