Missing service_type in endpoint filtering data

[Ayumu Ueha]

Hi, Blazar team,
I'm Ueha from tacker team, we are using python-blazarclient and we started getting errors a few days ago.

I see below patch [1] that merged in Aug 27.

[1] https://review.opendev.org/c/openstack/python-blazarclient/+/781592

As a patch[1] change, "service_type" is added to the argument of the Client class, but it is not used in the Client class.
Originally, "service_type" was specified in *args, but the patch seems to prevent "service_type" from being passed to "importutils.import_object()".

This causes the following error:

```
tacker.tests.functional.legacy.vnfm.test_tosca_vnf_reservation.VnfTestReservationMonitor.test_vnf_alarm_scale_with_instance_reservationtesttools.testresult.real._StringException: pythonlogging:'': {{{2021-08-31 15:23:05,503 73222 WARNING [keystoneauth.identity.base] Plugin cannot return an endpoint without knowing the service type that is required. Add service_type to endpoint filtering data.}}}

Traceback (most recent call last):

Thanks.

This issue was fixed in the openstack/python-blazarclient 3.3.1 release.
