Handles API part implemented in change: I7c0a22c6a0287128d0c37e100589c78173fd9c1a So far passing configuration group was possible only for single instance deployment. As the trove api now already supports configuration attach and detach for clusters, we are able to handle it in client. Configuration will be applied to each cluster instance. Partially implements: blueprint cluster-configuration-groups Change-Id: Ic0840c995cbc34203c76494d7ba522f3e17141a7 Signed-off-by: Marcin Piwowarczyk <m.piwowarczy@samsung.com>
