Make blocking wait on running workers/deployments optional

[mfocko]

deployment/playbooks/deploy.yml

Lines 429 to 433 in 848a1dd

	- name: Wait for worker-long-running-0 to be running
	vars:
	pod_name: packit-worker-long-running-0
	ansible.builtin.include_tasks: tasks/wait_for_pod.yml
	when: workers_long_running > 0

Currently somewhat broken, expects the CLI to be switched to the correct project + does not really make sense to be present in the playbook?

Notes

• Testing Farm deployment tests depend on this, could be just moved around
• Usefulness during manual deployments is questionable…
• We could probably keep it as an optional thing via tag / variable, such as wait/blocking
• Keep in mind testing the deployment on the TF when refactoring this
