Add email-based password reset (#1779) 
* Add email-based password reset

Fixes #734

* rename SETPASS to RESETPASS

* review fixes

* abuse mitigations

* SENDPASS and RESETPASS should both touch the client login throttle
* Produce a logline and a sno on SENDPASS (since it actually sends an email)

* don't re-retrieve the settings value

* add email confirmation for NS SET EMAIL

* smtp: if require-tls is disabled, don't validate server cert

* review fixes

* remove cooldown for NS SET EMAIL

If you accidentally set the wrong address, the cooldown would prevent you
from fixing your mistake. Since we touch the registration throttle anyway,
this shouldn't present more of an abuse concern than registration itself.

# This is the "traditional" or "mainstream" config file for Ergo.
# It tries to replicate the behavior of other ircds, at the cost of not
# taking full advantage of Ergo's features. This config is suitable for use
# in IRCv3 conformance testing.
# network configuration
network:
# name of the network
name: ErgoTest
# server configuration
server:
# server name
name: ergo.test
# addresses to listen on
listeners:
# This version of the config provides a public plaintext listener on
# port 6667 for testing and compatibility with legacy applications.
# We recommend disabling this listener in a production setting
# and replacing it with loopback-only listeners (see default.yaml):
":6667":
# The standard SSL/TLS port for IRC is 6697. This will listen on all interfaces:
":6697":
# this is a standard TLS configuration with a single certificate;
# see the manual for instructions on how to configure SNI
tls:
cert: fullchain.pem
key: privkey.pem
# 'proxy' should typically be false. It's for cloud load balancers that
# always send a PROXY protocol header ahead of the connection. See the
# manual ("Reverse proxies") for more details.
proxy: false
# optionally set the minimum TLS version (defaults to 1.0):
# min-tls-version: 1.2
# Example of a Unix domain socket for proxying:
# "/tmp/ergo_sock":
# Example of a Tor listener: any connection that comes in on this listener will
# be considered a Tor connection. It is strongly recommended that this listener
# *not* be on a public interface --- it should be on 127.0.0.0/8 or unix domain:
# "/hidden_service_sockets/ergo_tor_sock":
# tor: true
# Example of a WebSocket listener:
# ":8097":
# websocket: true
# tls:
# cert: fullchain.pem
# key: privkey.pem
# sets the permissions for Unix listen sockets. on a typical Linux system,
# the default is 0775 or 0755, which prevents other users/groups from connecting
# to the socket. With 0777, it behaves like a normal TCP socket
# where anyone can connect.

# with the recommended default of 'precis', UTF8 identifiers that are "sane"
# (according to RFC 8265) are allowed, and the server additionally tries to protect
# against confusable characters ("homoglyph attacks").
# the other options are 'ascii' (traditional ASCII-only identifiers), and 'permissive',
# which allows identifiers to contain unusual characters like emoji, but makes users
# vulnerable to homoglyph attacks. unless you're really confident in your decision,
# we recommend leaving this value at its default (changing it once the network is
