no longer use oslo-incubator code
As part of the first community-wide goal [1], teams were asked to remove the openstack/common package of their projects if one existed. This was a byproduct of the old oslo-incubator form of syncing common functionality. - Most of the apiclient package was not actually used in code, only the exceptions were. So remove most of it. - Copy the exceptions from apiclient to an existing top level location. - Create an i18n module to remove the gettextutils dependency, this creates a new requirement - oslo.i18n. - Remove a test (test_base) since it was testing the functionality of apiclient.base, which was not used in congressclient. - General cleanup to other openstack/common references [1] http://governance.openstack.org/goals/ocata/remove-incubated-oslo-code.html Change-Id: I2f7f5d2d43e6a5c2e4dfe35266951efb4293093d
