Enhance Stack Advisor to support Blueprint recommendation

      StackAdvisor component as of now can recommend and validate component layout and configurations. Precisely, we can
      request StackAdvisor API for any of these recommendations (host_groups, configurations, configuration-dependencies).

      StackAdvisor has got the host specific resouce details (memory, cpu, disks, os type, etc.,) but it does not use these details while recommending the host-component mapping though configuration recommendation is making use of it.

      Applications/Service Providers that are using Amabri Rest API/Blueprints to provision and manage Hadoop clusters will largely benefit if Stack Advisor component is enhanced to address following GAPs

      • Support for Heterogenous hosts (Master, Slaves, Clients)
      • Provide both host group and configuration recommendations in same blueprint output response instead of requesting one at
        a time (as of now we can request one of the following - host_groups, configurations, configuration-dependencies not a combination/al of them)
      • Provide HA blueprint recommendation in stack advisor (creating handcrafted blueprint without using StackAdvisor limits
        the potential of StackAdvisor component)
      • Recommend appropriate hosts to services based on the host resource availability and service resource requirements
