Description

Python code at at common-services level used generic imports form resource_management (from resource_management import *)
Ideally, for easier code tracking and performance, these import should be more specific, such as:
from resource_management.libraries.script.script import Script
from resource_management.core.resources.system import Directory

This JIRA and subtasks will clean up import * from resource_management and replace it for specific imports
