deploy-steps-tasks/containers: set concurrency to 2 

After some testing, it seems like podman run/exec/create commands can be
run at the same time and decrease the deployment time when 2 commands
(maximum) at the same time are run.

Example of benchmark done for an Undercloud deployment in my local environment:
- With Paunch enabled: 26 min
- With Paunch disabled and concurrency set to 1: 32 min
- With Paunch disabled and concurrency set to 2: 29 min
- With Paunch disabled and concurrency set to 3: 33 min

(Above 4, results are worse).
