> *Current:* HSI config *'num_llap_nodes_for_llap_daemons*' is calculated and recommended
via Stack Advisor during Blueprint install and *''num_llap_nodes''*  value is not used for
*'num_llap_nodes_for_llap_daemons*' calculation, if available in Blueprint.
> *Issue* :  This creates the problem of calculating value for *'num_llap_nodes_for_llap_daemons'*,
in which calculation doesn't includes using the *'num_llap_nodes'* value.
> We need to use *'num_llap_nodes'* config value (if provided in BP) while calculating
value for *'num_llap_nodes_for_llap_daemons'* during cluster creation call to Stack Advisor.
> *Fix* : During BP cluster install call to SA, recommendation for *'num_llap_nodes_for_llap_daemons'*
should use value of *'num_llap_nodes'* config if specified in the cluster BP call.
