neutron should log user_name and project_name by default like in nova
neutron should log user_name and project_name by default like in nova

neutron doesn't log user_name and project_name along side req-id in
devstack logs. So, Openstack jenkins neutron check and gate jobs also
not logging user_name and project_name along side req-id.
Without knowing the user and tenant, its hard to understand what the
logs are doing when multiple tenants are using the cloud.

Nova is logging user_name and project_name by default.
So porting the same changes to neutron.
