2328: Feature: Configurable default spam threshold used for new users r=mergify[bot] a=enginefeeder101
## What type of PR?
Feature
## What does this PR do?
This PR adds functionality to set a custom default spam threshold
for new users. The environment variable ``DEFAULT_SPAM_THRESHOLD`` is
used for this purpose. When not set, it defaults back to 80%, as the
default value was before.
If ``DEFAULT_SPAM_THRESHOLD`` is set to a value that Python cannot
parse as an integer, a ValueError is thrown. There is no error handling
for that case built-in. Should that be done?
