New release: dnscontrol v3.18.0

[Tom Limoncelli]

https://github.com/StackExchange/dnscontrol/releases/tag/v3.18.0

This release includes 1 new provider, some features work better, and
there are many, many bug fixes.

Thanks to Simen Bai for contributing a provider for Domainnameshop!
Thanks to Amelia Aronsohn for stepping up to be the new owner of
DNSIMPLE, who has already made numerous improvements!

Many providers have improved TXT record handling thanks to some new
tests that surfaced some bugs. GCLOUD users can now use ADC for
authentication. The code that populates a new zone in HETZNER and
ROUTE53 now works better. The `get-zones` command generates code
that needs less hand-editing (but still is "a good first draft", not
perfect). The JS version of the SPF flatterer has been recompiled with
the latest gopherjs.

## Depreciation warnings

* **Call for new volunteer maintainers for NAMEDOTCOM, and
SOFTLAYER.** These providers have no maintainer. Maintainers respond
to PRs and fix bugs in a timely manner, and try to stay on top of
protocol changes.
* **ACME/Let's Encrypt support is frozen and will be removed after
December 31, 2022.** The `get-certs` command (renews certs via Let's
Encrypt) has no maintainer. There are other projects that do a better
job. If you don't use this feature, please do not start. If you do use
this feature, please plan on migrating to something else. See
discussion in https://github.com/StackExchange/dnscontrol/issues/1400
* **convertzone is frozen and will be removed after June 30, 2022.**
The `convertzone` stand-alone program is replaced by the `get-zone`
subcommand of DNSControl. It does everything `convertzone` did and
more.
* **Provider ACTIVEDIRECTORY_PS is frozen and will be removed after
June 30, 2022.** It is replaced by MSDNS which is 100% feature
compatible and works better. (We believe nobody uses it.)
* **get-zones syntax changes in v3.16** Starting in v3.16, the command
line arguments for `dnscontrol get-zones` changes. For backwards
compatibility change `provider` to `-`. See documentation for details.
