Create VM Memory agent and common bundles
This commit extracts VM Memory data collection from SystemBackend and
related classes into a vm-memory-agent bundle. It also moves the
VmMemoryStatDAO from common-core into a vm-memory-common bundle that
registers the DAO once Storage is available. This also removes the DAO
from DAOFactory.
This also temporarily adds the vm-memory-common bundle as a dependency
to client-cli until my later dynamic vm-stat patch.
