[dnsmasq] Retry restarting dnsmasq

On busy host, if the restart is performed, Ansible is not waiting enough
of time to continue. Sometimes it happens that the service was
configured few seconds after the Ansible task that require it was
executed.
Retry and wait for dnsmasq to be restarted before continuation.
