* Fix TTL mismatch leading to HTTP 412
This PR is a follow up from #8521 where we address the
issue of potentially having a mismatch of TTL when executing
a DNS change (transaction = deletion + additions). Let's say
we have a record `foo.org 30 IN TXT foo-content` with TTL 30s,
when creating challenge or cleaning we might need to perform
a deletion operation in the transaction. Currently certbot
would ask Google API to delete the foo record like this:
`foo.org 60 in TXT foo-content` ignoring the record's original
TTL and using 60s instead. This leads to HTTP 412 as Google would
expect a perfect match of what we want to delete with what it is
on the DNS. See also #8523
* remove ttl from default data to avoid confusions
* Refactor tests and add a missing case
This commit adds a test that covers the case when we are
deleting a TXT record which contains a single rrdatas. Also,
refactoring a couple of tests.
* Make get_existing_txt_rrset documentation more precise about return value
* Add missing assertions in tests.
* fix linting issues
* Mention fix on changelog
* Explain fix around user impact
* Explain what happens when no records are returned
* Update certbot/CHANGELOG.md
* Update certbot/CHANGELOG.md
* Fix fetch of existing records from Google DNS
There has been many complaints regarding `certbot_dns_google` plugin
failing with:
* HTTP 412 - Precondition not met
* HTTP 409 - Conflict
See #6036. This PR fixes that situation. The bug lies on how we
fetch the TXT records from google. For large amount of records
the Google API paginates the result but we ignore the subsequent
pages and assume that if the record is not in the first response then
it doesn't exist. This leads to either HTTP 409, or HTTP 412 or both.
In this PR we leverage the use of filters on the API to get exactly
the records we are looking for. Apart from fixing the problem stated
above, it has the extra benefit of making the process faster by
reducing the amount of API calls and it doesn't require us to handle
any pagination logic
* Explain changes on CHANGELOG
* Edit AUTHORS.md
* make execute static
* Update certbot/CHANGELOG.md
Being more specific for which plugin this fix bug is meant for.

This adds a 'Error parsing credentials file ...' wrapper to any errors
raised inside certbot-dns-google's usage of oauth2client, to make it
obvious to the user where the problem lies.
Part of #7886.
This PR conditionally installs `mock` in `certbot-dns-*/setup.py` based on setuptools version and python version, when possible. It then updates the tests to use `unittest.mock` when `mock` isn't available.
* Do not require mock in Python 3 in certbot-dns modules
* update changelog
* error when trying to build wheels with old setuptools
* add type: ignores

This PR makes appropriate corrections to run pylint on Python 3.
Why not keeping the dependencies unchanged and just run pylint on Python 3?
Because the old version of pylint breaks horribly on Python 3 because of unsupported version of astroid.
Why updating pylint + astroid to the latest version ?
Because this version only fixes some internal errors occuring during the lint of Certbot code, and is also ready to run gracefully on Python 3.8.
Why upgrading mypy ?
Because the old version does not support the new version of astroid required to run pylint correctly.
Why not upgrading mypy to its latest version ?
Because this latest version includes a new typshed version, that adds a lot of new type definitions, and brings dozens of new errors on the Certbot codebase. I would like to fix that in a future PR.
That said so, the work has been to find the correct set of new dependency versions, then configure pylint for sane configuration errors in our situation, disable irrelevant lintings errors, then fixing (or ignoring for good reason) the remaining mypy errors.
I also made PyLint and MyPy checks run correctly on Windows.
