An early version of the spec indicated that clients should process issuance
sequentially, following Link rel=next from an account URL to an authz URL, to a
new-cert URL. However, the spec has long since moved to putting these URLs in
the directory.
Certbot nominally supports either; This change consolidates on always using the
directory, simplifying things and making the transition to the latest ACME spec
easier.
* Revert "Revert "Remove Link rel=next for authzs and new-certs." (#4277)"
This reverts commit 11ec1eb911.
* Save new_authzr_uri with account for older clients.
* Add test that new_authzr_uri exists in regr.
* Restore backwards compatibility for new_authzr_uri.
* Fix account_test.
* Add test for deprecated URI argument to request_challenges.
* Review feedback.
* Fix test
* Add omitempty to new_cert_uri.
