Log Message:
py-certbot: updated to 0.40.1

0.40.1:

Changed
Added back support for Python 3.4 to Certbot components and certbot-auto due to \ 
a bug when requiring Python 2.7 or 3.5+ on RHEL 6 based systems.
More details about these changes can be found on our GitHub repo.

0.40.0:

Changed
We deprecated support for Python 3.4 in Certbot and its ACME library. Support \ 
for Python 3.4 will be removed in the next major release of Certbot. \ 
certbot-auto users on RHEL 6 based systems will be asked to enable Software \ 
Collections (SCL) repository so Python 3.6 can be installed. certbot-auto can \ 
enable the SCL repo for you on CentOS 6 while users on other RHEL 6 based \ 
systems will be asked to do this manually.
--server may now be combined with --dry-run. Certbot will, as before, use the \ 
staging server instead of the live server when --dry-run is used.
--dry-run now requests fresh authorizations every time, fixing the issue where \ 
it was prone to falsely reporting success.
Updated certbot-dns-google to depend on newer versions of \ 
google-api-python-client and oauth2client.
The OS detection logic again uses distro library for Linux OSes
certbot.plugins.common.TLSSNI01 has been deprecated and will be removed in a \ 
future release.
CLI flags --tls-sni-01-port and --tls-sni-01-address have been removed.
The values tls-sni and tls-sni-01 for the --preferred-challenges flag are no \ 
longer accepted.
Removed the flags: --agree-dev-preview, --dialog, and --apache-init-script
acme.standalone.BaseRequestHandlerWithLogging and \ 
acme.standalone.simple_tls_sni_01_server have been deprecated and will be \ 
removed in a future release of the library.
certbot-dns-rfc2136 now use TCP to query SOA records.

Fixed
