log_handler is not used any more by Ceilometer project, but still listed on openstack-common.conf, this patch fixes it. Note: oslo-incubator.timeutils is not used by oslo-incubator modules any more after we do code sync, this patch removes it too. gettextutils has graduated from oslo-incubator, we should port our project to use oslo.i18n. To use oslo.i18n conveniently, this patch introduces a helper module ceilometer.i18n, which is stolen from Nova. Note: gettextutils.install is deprecated, see: http://docs.openstack.org/developer/oslo.i18n/usage.html#creating-an-integration-module Note: _ is removed from builtins in tox.ini since we're not using install any more.
