Extend APEX CLIEditor to generate policy in ToscaServiceTemplate format

Currently apex CLIEditor is used to generate a json policy model from
apex CLI language (.apex) file.
As per the new  LifeCycle API, the policies are expected to be defined
as ToscaServiceTemplate. Hence, the current CLIEditor is extended to
generate the policies in ToscaServiceTemplate way.
