Fix Prometheus template generation

Browse Source 
In a deployment where Prometheus is enabled and
Alertmanager is disabled the task "Copying over
prometheus config file" in
'ansible/roles/prometheus/tasks/config.yml' will
fail to template the Prometheus configuration file
'ansible/roles/prometheus/templates/prometheus.yml.j2'
as the variable 'prometheus_alert_rules' does not
contain the key 'files'. This commit fixes this bug.

In a deployment where Prometheus is enabled and Alertmanager is disabled the
configuration for the Prometheus will fail when templating as the variable
`prometheus_alert_rules` does not contain the key `files`. For details
