Allows some factorization of redundant code in stop_vm(), start_vm(),
create_vm() and main().
This new function also waits one extra second after a successful task execution as the API can be a bit ahead of Proxmox.
Before:
TASK [ansible-role-proxmox-instance : Ensure test-instance is created]
changed: [localhost]
TASK [ansible-role-proxmox-instance : Ensure test-instance is updated]
fatal: [localhost]: FAILED! => changed=false
msg: VM test-instance does not exist in cluster.
After:
TASK [ansible-role-proxmox-instance : Ensure test-instance is created]
changed: [localhost]
TASK [ansible-role-proxmox-instance : Ensure test-instance is updated]
changed: [localhost]
