py-acme py-certbot*: updated to 1.16.0

Certbot 1.16.0

Changed

DNS plugins based on lexicon now require dns-lexicon >= v3.1.0
Use UTF-8 encoding for renewal configuration files
Windows installer now cleans up old Certbot dependency packages
before installing the new ones to avoid version conflicts.
This release contains a substantial command-line UX overhaul,
based on previous user research. The main goal was to streamline
and clarify output. If you would like to see more verbose output, use
the -v or -vv flags. UX improvements are an iterative process and
the Certbot team welcomes constructive feedback.
Functions certbot.crypto_util.init_save_key and certbot.crypto_util.init_save_csr,
whose behaviors rely on the global Certbot config singleton, are deprecated and will
be removed in a future release. Please use certbot.crypto_util.generate_key and
certbot.crypto_util.generate_csr instead.

Fixed

Fix TypeError due to incompatibility with lexicon >= v3.6.0
Installers (e.g. nginx, Apache) were being restarted unnecessarily after dry-run renewals.
Colors and bold text should properly render in all supported versions of Windows.
