This patch extends the configuration task for prometheus
to allow the operator to pass a(set) of prometheus alert
rules files, that will be used by alertmanager to produce
alerts.

This functionality is only enabled when the prometheus-alertmanager
service is enabled.

Change https://review.openstack.org/#/c/571826/4/


introduced the usage of merge_yaml for rendering the
prometheus-alertmanager.yml configuration.

However the merge_yaml module doesn't do a deep copy of >=
second level properties, so it doesn't works for
most configurations.

Implements: blueprint resource-constraints

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

In change I78cb60168aaa40bb6439198283546b7faf33917c, action was changed
to kolla_action, and serial to kolla_serial, to avoid Ansible warnings
due to use of reserved keywords. In that change, some keywords were
missed, and some changes that were merged since then have not switched
to the new variables. This change fixes all current instances of those
issues.
