Allow Synapse to send registration emails + choose Synapse or an external server to handle 3pid validation (#5987)

This is a combination of a few different PRs, finally all being merged into `develop`:

* #5875 
* #5876 
* #5868 (This one added the `/versions` flag but the flag itself was actually [backed out](891afb57cb (diff-e591d42d30690ffb79f63bb726200891)) in #5969. What's left is just giving /versions access to the config file, which could be useful in the future)
* #5835 
* #5969 
* #5940

Clients should not actually use the new registration functionality until https://github.com/matrix-org/synapse/pull/5972 is merged.

UPGRADE.rst, changelog entries and config file changes should all be reviewed closely before this PR is merged.

Upgrading to v1.4.0
===================
Config options
--------------
**Note: Registration by email address or phone number will not work in this release unless
some config options are changed from their defaults.**
This is due to Synapse v1.4.0 now defaulting to sending registration and password reset tokens
itself. This is for security reasons as well as putting less reliance on identity servers.
However, currently Synapse only supports sending emails, and does not have support for
phone-based password reset or account registration. If Synapse is configured to handle these on
its own, phone-based password resets and registration will be disabled. For Synapse to send
emails, the ``email`` block of the config must be filled out. If not, then password resets and
registration via email will be disabled entirely.
This release also deprecates the ``email.trust_identity_server_for_password_resets`` option and
replaces it with the ``account_threepid_delegates`` dictionary. This option defines whether the
homeserver should delegate an external server (typically an `identity server
<https://matrix.org/docs/spec/identity_service/r0.2.1>`_) to handle sending password reset or
registration messages via email and SMS.
If ``email.trust_identity_server_for_password_resets`` is set to ``true``, and
``account_threepid_delegates.email`` is not set, then the first entry in
``trusted_third_party_id_servers`` will be used as the account threepid delegate for email.
This is to ensure compatibility with existing Synapse installs that set up external server
handling for these tasks before v1.4.0. If ``email.trust_identity_server_for_password_resets``
is ``true`` and no trusted identity server domains are configured, Synapse will throw an error.
If ``email.trust_identity_server_for_password_resets`` is ``false`` or absent and a threepid
type in ``account_threepid_delegates`` is not set to a domain, then Synapse will attempt to
send password reset and registration messages for that type.
Email templates
---------------
If you have configured a custom template directory with the ``email.template_dir`` option, be
aware that there are new templates regarding registration. ``registration.html`` and
``registration.txt`` have been added and contain the content that is sent to a client upon
registering via an email address.
``registration_success.html`` and ``registration_failure.html`` are also new HTML templates
that will be shown to the user when they click the link in their registration emai , either
showing them a success or failure page (assuming a redirect URL is not configured).
Synapse will expect these files to exist inside the configured template directory. To view the
default templates, see `synapse/res/templates
<https://github.com/matrix-org/synapse/tree/master/synapse/res/templates>`_.

for more details on these settings.
New email templates
---------------
Some new templates have been added to the default template directory for the purpose of the
homeserver sending its own password reset emails. If you have configured a custom
``template_dir`` in your Synapse config, these files will need to be added.
``password_reset.html`` and ``password_reset.txt`` are HTML and plain text templates
respectively that contain the contents of what will be emailed to the user upon attempting to
reset their password via email. ``password_reset_success.html`` and
``password_reset_failure.html`` are HTML files that the content of which (assuming no redirect
URL is set) will be shown to the user after they attempt to click the link in the email sent
to them.
