Config service manager implementation.

Added new service for managing the service(RMCP+, ssh, web)
properties like state, port, channel etc. This is common
service supports both systemctl and iptables.

Example usage: Blocking specific service port and restricting
network traffic on specific channels etc.

Unit Test:
 - Changed port of RMCP+ service and validated.
 - Restricted network traffic on specific channel(eth0)
    and cross validated functionality.
