After removal of apiclient from oslo-incubator, it was
copied to magnumclient repo with following patch:
https://review.openstack.org/#/c/280050
Most of the Classes/Methods from apiclient.base are
not used, so with this patch they are removed.

Closes-Bug: #1644167
Apiclient[1] and cliutils[2] is removed form Oslo incubator, we should keep
the local copy by ourself.
1. copy openstack/common/apiclient to common/apiclient
2. only keep base, auth, exceptions from apiclient, others are unused
3. copy openstack/common/cliutils.py to common/cliutils.py
4. update all magnumclient.openstack.common.* users to use
magnumclient.common.*
This is the first step to delete openstack common modules.
