This patch extends the prometheus role for being able to deploy the prometheus-alertmanager[0] container. The variable enable_prometheus_alertmanager decides if the container should be deployed and enabled. If enabled, the following configuration and actions are performed: - The alerting section on the prometheus-server configuration is added pointing the prometheus-alertmanager host group as targets. - HAProxy is configured to load-balance over the prometheus-alertmanager host group. (external/internal). Please note that a default (dummy) configuration is provided, that allows the service to start, the operator should extend it via a node custom config [0] https://github.com/openstack/kolla/tree/master/docker/prometheus/prometheus-alertmanager Change-Id: I3a13342c67744a278cc8d52900a913c3ccc452ae Closes-Bug: 1774725 Signed-off-by: Jorge Niedbalski <jorge.niedbalski@linaro.org>
