> When using a stack-version which does not have a stack-advisor, exceptions are output to log that a stack-advisor.py file is not present. Since stack-advisor functionality is optional for a stack-version, we should print out message saying "StackAdvisor implementation for stack HDP, version 2.3.ECS was not found" instead of throwing exceptions.
