+Subject: Fix fernet audit ids for v2.0
+
+The fernet token provider was doing some weird things with audit ids that
+caused token rescoping to not work because audit ids were never pulled from the
+original token. This commit also enables some tests for v2.0 authentication
+with the Fernet as the token provider.
+
+Closes-Bug: 1577558

+(cherry picked from commit 0d376025bae61bf5ee19d992c7f336b99ac69240)
