slack_incoming webhook previously used has_request_variables to
extract payload from HttpRequest object first, before trying to
access HttpRequest.body again in view.py. This caused an error
when one sends a request without payload - it is forbidden to
read from request data stream twice.
Instead of relying on has_request_variables, this PR extracts
payload depending on content type in view.py directly to avoid
reading request data stream twice.
Fixes#19056.

Commit ab8aae6d0c (#12161) incorrectly
assumed that ‘new’ is a string. In the case of change == "links",
it’s a dict.

Adds request as a parameter to json_success as a refactor towards
making `ignored_parameters_unsupported` functionality available
for all API endpoints.
Also, removes any data parameters that are an empty dict or
a dict with the generic success response values.
As a consequence:
• Bump minimum supported Python version to 3.7.
• Move Vagrant environment to Debian 10, which has Python 3.7.
• Move CI frontend tests to Debian 10.
• Move production build test to Debian 10.

django.utils.translation.ugettext is a deprecated alias of
django.utils.translation.gettext as of Django 3.0, and will be removed
in Django 4.0.
Commit e7ed907cf6 (#18174) fixed this
before, but new instances have been added.

Prior to this commit, we wrapped all incoming messages from Slack
in backticks. This led to weird formatting errors when an incom-
ing message from Slack contains backticks, to refer to a function
name, for instance.
We recently ran into a payload in production that didn't contain
an event type at all. A payload where we can't figure out the event
type is quite rare. Instead of letting these payloads run amok, we
should raise a more informative exception for such unusual payloads.
If we encounter too many of these, then we can choose to conduct a
deeper investigation on a case-by-case basis.
With some changes by Tim Abbott.
