Missing information in log message for Invalid tunnel type

[Alexandros Soumplis]

When a host has an invalid tunnel type, neutron-api raises an error like the following:

2020-02-18 06:25:10.258 1170 ERROR oslo_messaging.rpc.server [req-97f7791d-d58d-4315-b7f9-3516f790c46b - - - - -] Exception during message handling: neutron_lib.exceptions.InvalidInput: Invalid input for operation: Network type value 'gre' not supported.

This info does not help track the offending host, we need the host name and tunnel ip logged.

    Improve log message on exception for invalid tunnel type

    exception is raised but does not contain info for the offending host.
