When SSO is enabled, with PyJWT >= 2 and python3, login via SSO fails with:

Internal Server Error
Traceback (most recent call last):
File "/usr/share/ceph/mgr/dashboard/services/exception.py", line 47, in dashboard_exception_handler

token = token.decode('utf-8')
AttributeError: 'str' object has no attribute 'decode'

This is because tokens in PyJWT are already str objects. To fix this the token.decode line in controllers/saml2.py is adapted to match the form used in controllers/auth.py to avoid this error.
