Keystone Access Log logs "python-keystoneclient" as User-Agent even when request is made by openstack client

[Roxana Gherle]

Whenever we execute an openstack cli command, Keystone logs "python-keystoneclient" as User Agent in Keystone access log. We should probably log python-openstackclient as the User Agent since that is the correct original User Agent.

This would add some useful information for debugging instead of always seeing python-keystoneclient in the logs.

    Send the correct user-agent to Keystone

    When we execute an Openstack CLI command, keystone should log in
    Keystone access log that the user-agent that made the request was
    'python-openstackclient' instead of the default 'python-keystoneclient'.
    Therefore, when we create the authentication session we
    need to send the explicit user-agent.
