<!-- Thanks for the contribution, this is awesome. -->

# PR Details
## Description

Creating relevant scenario, routing, sumo files for background traffic
for Town 05.

Possible options:
1. https://sumo.dlr.de/docs/Tools/Trip.html to generate random route
files given input parameters
2. https://sumo.dlr.de/docs/od2trips.html (origin destination) allows
you to configure origin and destination as well as intermediate edges to
use.
3.
https://sumo.dlr.de/docs/Definition_of_Vehicles%2C_Vehicle_Types%2C_and_Routes.html#incomplete_routes_trips_and_flows
similar to od2trips but allows for definition of traffic flows (multiple
vehicles that follow an origin/destination route).

In this PR:
1. Option 1 has been selected and background traffic route file for
Town05 has been generated using sumo tools **randomTrips.py**.
2. A bash script genrate_random_traffic.sh has been written to generate
background traffic for given sumo network of Town05 which can be
utilized to generate background traffic for other maps and uses case's
requirement
3. A new directory named tools has been created to store the script
genrate_random_traffic.sh under Co-simulation Directory
