feat(ansible): Install tuned for performance tuning

[hunleyd]

This commit introduces the tuned service to the Ansible playbook to enable dynamic system performance optimization.

The changes include:

• A new task ansible/tasks/setup-tuned.yml is created to handle the installation of the tuned package via apt.
• The main ansible/playbook.yml is updated to import and execute this new task.
• The installation is conditional and only runs when the stage2_nix variable is true, allowing for flexibility in different build stages.

By installing tuned, the system can be better optimized for various workloads, which is particularly beneficial for database performance.

note that tuned is not enabled nor configured in this PR. that'll come later.

i think this is good but wonder what tests we'll apply before promoting it to our release and production?

In this PR we're simply ensuring the binary is installed. Ansible takes care of ensuring that happens. I'm not sure what else we'd need to test unless we want to verify /usr/bin/tuned is present? Or are you thinking more about checking that it's not started? @samrose
