And update the upgrade notes to point at old versions of the documentation.

Switching to a sequence means there's no need to track `last_txn` on the
AS state table to generate new TXN IDs. This also means that there is
no longer contention between the AS scheduler and AS handler on updates
to the `application_services_state` table, which will prevent serialization
errors during the complete AS txn transaction.

This document isn't really relevant any more, and its existence is more confusing than helpful.

Also remove support for non-HTTP(S) web_client_location.

This changes the behaviour of the root endpoint to redirect
directly to the configuration of `web_client_location` if it is
given an HTTP(S) URL.

Remove deprecated delete room admin API,
`POST /_synapse/admin/v1/rooms/<room_id>/delete`

* Labeled a lot more code blocks with the appropriate type
* Fixed a couple of minor typos (missing/extraneous commas)

URL cache files are short-lived and it does not make sense to offload
them (eg. to the cloud) or back them up.

Also refactors some of the registration of endpoints on workers.

When a user deletes an email from their account it will
now also remove all pushers for that email and that user
(even if these pushers were created by a different client)

Several configuration sections are using separate settings for custom template directories, which can be confusing. This PR adds a new top-level configuration for a custom template directory which is then used for every module. The only exception is the consent templates, since the consent template directory require a specific hierarchy, so it's probably better that it stays separate from everything else.
