    Make osc plugin work again

    while moving to SessionClient the OSC plugin
    was forgotten to be amended accordingly.

    Besides, the keystoneauth Adapter's request method
    returns a single response object, not a tuple.

    This commit also updates relevant requirements to be
    in sync with global OpenStack ones.

[Viktor (viktorsvecov)]

I have got similar error message with 0.4.0-0ubuntu1 version installed on Ubuntu 20.04 using python3-pankoclient package.

[(openstack1_admin)]# openstack event list
__init__() got an unexpected keyword argument 'endpoint'

In latest version (1.1.0) the error is gone.

Perhaps it was the same problem.
