Disable network temporarily on repeated connection failures

Previously, only explicit indications of authentication failures were
used to disable a network block temporarily. Extend this to use multiple
failed connection attempts as a sign of a possible authentication or
authorization failure to reduce the frequency of connection attempts
with a network that does not seem to allow connection.
