Clarify the account_validity and email sections of the sample configuration. (#6685)
Generally try to make this more comprehensible, and make it match the
conventions.

I've removed the documentation for all the settings which allow you to change
the names of the template files, because I can't really see why they are
useful.

#
# Once this feature is enabled, Synapse will look for registered users without an
# expiration date at startup and will add one to every account it found using the
# current settings at that time.
# This means that, if a validity period is set, and Synapse is restarted (it will
# then derive an expiration date from the current validity period), and some time
# after that the validity period changes and Synapse is restarted, the users'
# expiration dates won't be updated unless their account is manually renewed. This
# date will be randomly selected within a range [now + period - d ; now + period],
# where d is equal to 10%% of the validity period.
#

# feature.

#period: 6w
# The amount of time before an account's expiry date at which Synapse will
# send an email to the account's email address with a renewal link. By
# default, no such emails are sent.
#
# If you enable this setting, you will also need to fill out the 'email' and
# 'public_baseurl' configuration sections.

# The subject of the email sent out with the renewal link. '%%(app)s' can be
# used as a placeholder for the 'app_name' parameter from the 'email'
# section.
#
# Note that the placeholder must be written '%%(app)s', including the

# Set the number of bcrypt rounds used to generate password hash.

# The list of identity servers trusted to verify third party
# identifiers by this server.
#
# Also defines the ID server which will be called when an account is
# deactivated (one will be picked arbitrarily).
#
# Note: This option is deprecated. Since v0.99.4, Synapse has tracked which identity
# server a 3PID has been bound to. For 3PIDs bound before then, Synapse runs a
# background migration script, informing itself that the identity server all of its
# 3PIDs have been bound to is likely one of the below.
#
# As of Synapse v1.4.0, all other functionality of this option has been deprecated, and
# it is now solely used for the purposes of the background migration script, and can be
# removed once it has run.
#trusted_third_party_id_servers:
# - matrix.org
# - vector.im
# Handle threepid (email/phone etc) registration and password resets through a set of
# *trusted* identity servers. Note that this allows the configured identity server to
# reset passwords for accounts!
#
# Be aware that if `email` is not set, and SMTP options have not been
# configured in the email config block, registration and user password resets via
# email will be globally disabled.
#
# Additionally, if `msisdn` is not set, registration and password resets via msisdn
# will be disabled regardless. This is due to Synapse currently not supporting any
# method of sending SMS messages on its own.
#
# To enable using an identity server for operations regarding a particular third-party
# identifier type, set the value to the URL of that identity server as shown in the
# examples below.
#
# Servers handling the these requests must answer the `/requestToken` endpoints defined
# by the Matrix Identity Service API specification:
# https://matrix.org/docs/spec/identity_service/latest
#
# If a delegate is specified, the config option public_baseurl must also be filled out.
