Setting Issue Security Level Based on Parent Component

Using ScriptRunner and Subcomponents feature you can set issue security level based on parent components. Even if you have hundreds of subcomponents you can define a mapping between top level components and security level which is a lot easier to maintain. Assuming you have component hierarchy on the right. Following script updates issue's security level based on the mapping defined on the lines 21-24 of the script.
