    Set 'deployed_before' attribute in cluster attributes if not present

    Before this change if master node had been upgraded to Fuel of
    versions >= 8.0, attempt to re/deploy existing clusters would have failed
    as attributes of those clusters would have lack 'deployed_before' field.

    Since processing of the flag is temporary solution it should not be
    coded in data base migration logic. Thus the change introduces creating
    of the attribute with given value if it is not already present.
