Updated service.py and its dependencies
This is to avoid service module dependency on importutils that are now moved to oslo.utils. The following changes are included: * neutron/openstack/common/eventlet_backdoor.py 5d40e14 Remove code that moved to oslo.i18n 90ae24b Remove redundant default=None for config options fcf517d Update oslo log messages with translation domains * neutron/openstack/common/loopingcall.py 5d40e14 Remove code that moved to oslo.i18n e377393 Changes calcuation of variable delay ab5d5f1 Use timestamp in loopingcall bc48099 Log the function name of looping call fb4e863 Remove deprecated LoopingCall fcf517d Update oslo log messages with translation domains * neutron/openstack/common/service.py 5d40e14 Remove code that moved to oslo.i18n 6ede600 rpc, notifier: remove deprecated modules * neutron/openstack/common/systemd.py 17c4e21 Fix docstring indentation in systemd * neutron/openstack/common/threadgroup.py 5a1a016 Make stop_timers() method public fdc8883 Add graceful stop function to ThreadGroup.stop 2d06d6c Simple typo correction 4d18b57 threadgroup: use threading rather than greenthread Change-Id: I4887545f861a93223e2c7cbcdd39efe991bff547
