Advice hints must be disabled individually by setting the relevant
advice.* variables to false in the Git configuration. For server-side
and scripted usages of Git where hints aren't necessary, it can be
cumbersome to maintain configuration to ensure all advice hints are
disabled in perpetuity. This is a particular concern in tests, where
new or changed hints can result in failed assertions.
Add a --no-advice global option to disable all advice hints from being
displayed. This is independent of the toggles for individual advice
hints.
