Added clarifying comment to top of st2.tests2.conf
-# Config file used by integration tests
+# Config file used by Inquiry GC integration tests
+#
+# This config file exists because the Inquiry GC logic needs access to runners,
+# and the current way the config is used means we need our own "base_path" set.
+# Please see https://github.com/StackStorm/st2/issues/3775 for more information,
+# and please do not use this config file, as it will be deleted as soon as that
+# issue is addressed.
