PBM APIs break the API contract in vSphere 6.5 by raising
NotAuthenticated fault instead of SecurityError when session
is expired. We do catch NotAuthenticated faults (raised by
VIM APIs), but PBM APIs use the 'vim25' namespace which
result in not identifying the session expiry case. Therefore,
the session is not re-established. Fixing it by matching the
fault name suffix with 'NotAuthenticated' in the suds WebFault
exception handler
