    Check existence of ceph binaries in add-storage hook

    Add a check to make sure that the ceph package is installed in
    the add-storage shim. The add-storage hook is run prior to the
    install hook in order to provide storage for the install phase
    of the charm in cases where it is needed. The ceph-osd charm
    converts Juju storage into OSDs and doesn't need the storage
    for the install hook, so just skip the hook if its run early.
