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
