    AIO-SX: Fix adding OSD at runtime hanging when /dev/rbd* are mounted

    This mostly happens when stx-openstack application is running
    as there are a couple of pods that uses RBD PVCs.

    The reason of the hang is that, on AIO-SX, all OSDs are stopped
    while new ones are configured. This leads to data on the /dev/rbd*
    to be inaccessible when runtime puppet manifests executes
    'ceph-disk list' to query the state of all storage devices in
    the system.

    This commit removes the code that stops existing OSDs on all
    deployments. A side effect is a decrease in time needed to
    add the OSDs on a node with many OSDs already configured.
    For e.g. time for adding an OSD on a system with 7 OSDs can
    take more that 2 minutes, while with this change it drops to
    around 30 seconds.
