Use osc-lib instead of openstackclient

osc-lib is a package of common support modules for writing
OSC plugins. All common functions, classes such as exceptions,
utils, logs and so on have been moved from openstackclient to
osc-lib. So use osc-lib instead of openstackclient.

Since osc-lib 1.0.2 has released, it is stable to use.
