"""
This abstract class CliFcts defines the interface for the execution of any command-line-functions.
It uses the following configuration
  .a) COMP.conf->artifact->cli->[system] : for structural attributes of the operating-system \n
  .c) COMP.conf->conn->[cli] : for connection-attributes and structural attributes,
  maybe specialized for the operating-system

The attribute type resolves which technique is used, implemented in a specific tool-class:
  * cmd,bash,powersh ... for specific local operating-system
  * ssh,hadoop ... for specific remote operating-system
The main tasks are: \n
.1. executing the command-array - with attributes
   * conn.ip, host, port, user, password, ... for synchronous db-connection
   * conn.root, ... for path-definitions for file-implementations (csv, )
