This is a start to have different kinds of notifications. It is
possible to be notified via e-mail, matrix or gotify. It also extends
the current "periodic query" for due items by allowing notification
over different channels. A "generic periodic query" variant is added
as well.
Currently the query implementation cannot combine multiple/nested
fulltext searches within a query. It doesn't seem useful to have
shares based on fulltext searches, so it is disabled for now.
Issue: #446
The join to retrieve the attachment count per item turned out to be
very expensive. And it is not used anymore for the result, only to
support fulltext search. It is now removed from the query. The
DISTINCT keyword is also removed, because it is not necessary and it
is expensive. With the DISTINCT removed, a new index (provided in the
previous commit) can now be used to avoid sorting items.
The query now searches in more fields. For example, when getting a
list of tags, the query is applied to the tag name *and* category.
When listing persons, the query now also looks in the associated
organization name.
This has been used to make some headers in the meta data tables
clickable to sort the list accordingly.

The upload request can now contain a boolean for importing only
attachments when e-mails are uploaded. This option is now also added
to a source url.

Also hard delete the remaining items. They are empty (have no
attachments), because data is moved if possible. Doesn't make much
sense to keep them, because restoring them isn't much useful.
First, when checking for existence of a file, deleted items are not
conisdered.
The working with fulltext search has been changed: deleted items are
removed from fulltext index and are re-added when they are restored.
The fulltext index currently doesn't hold the item state and it would
mean much more work to introduce it into the index (or, worse, to
reprocess the results from the index). Thus, deleted items can only be
searched using database queries. It is probably a very rare use case
when fulltext search should be applied to deleted items. They have
been deleted for a reason and the most likely case is that they are
simply removed.
Refs: #347
In order to keep deleted items for a while, the periodic task can now
use a duration to only remove items with a certain age. This can be
used to ensure that a deleted item stays at least X days before it
will be removed from the database.

Before, there were periodic tasks run per collective and not user by
making sure that submitter + group are the same value. This is now
encoded in `UserTaskScope` so it is now obvious and errors can be
reduced when using this.
