Automating GNS3 lab setup via Ansible

[fracappa]

Description

This pull request introduces Ansible automation to streamline the GNS3 setup process. It replaces manual operations with automated tasks, making the setup more efficient and user-friendly.

Steps

1. Download the Cisco IOS Image
2. Start GNS3
3. Create a new template for the Cisco 2691 router
4. Configure the Xfce4 terminal in GNS3
5. Add the network-multitool docker image to the list of end devices

Step 2 is typically performed using the GUI. To enhance the process and ensure proper systemd integration, we have created a custom gns3.service file.

How Has This Been Tested?

This setup has been tested locally on the target host.

Thanks for the PR! Only thing, I'd use NFS for retrieving the needed files, as has been done here: https://github.com/netgroup-polito/CrownLabs/commit/be3ac2a7f97a97d8c55dfb563e679767a5648573 (search for matlab_nfs_source to see how it has been done).

I already created a volume and added the image inside, I can send you privately the details for testing.

@QcFe I have implemented the modifications as per your suggested. I introduced a variable called gns3_device_images, which points to an NFS path containing the required files. After testing it in a local environment, it appears to be functioning correctly. If you have any further feedback, please let me know

Done
