This commit follows up the work in Kolla to provide deploy and configure the
Prometheus blackbox exporter.
An example blackbox-exporter module has been added (disabled by default)
called os_endpoint. This allows for the probing of endpoints over HTTP
and HTTPS. This can be used to monitor that OpenStack endpoints return a status
code of either 200 or 300, and the word 'versions' in the payload.
This change introduces a new variable `prometheus_blackbox_exporter_endpoints`.
Currently no defaults are specified because the configuration is heavily
dependent on the deployment.

Currently, we have a lot of logic for checking if a handler should run,
depending on whether config files have changed and whether the
container configuration has changed. As rm_work pointed out during
the recent haproxy refactor, these conditionals are typically
unnecessary - we can rely on Ansible's handler notification system
to only trigger handlers when they need to run. This removes a lot
of error prone code.
This patch removes conditional handler logic for all services. It is
important to ensure that we no longer trigger handlers when unnecessary,
because without these checks in place it will trigger a restart of the
containers.

Many tasks that use Docker have become specified already, but
not all. This change ensures all tasks that use the following
modules have become:
* kolla_docker
* kolla_ceph_keyring
* kolla_toolbox
* kolla_container_facts
It also adds become for 'command' tasks that use docker CLI.

This patch implements the support for the elasticsearch-exporter in
kolla-ansible
The configuration and prechecks are reused from the other exporters

This patch implements the initial support for the
openstack-exporter[0] in the kolla-ansible
prometheus monitoring system.
The configuration and prechecks are reused from the other
exporters and a new template is provided for generating
a os-client-config file required by the exporter.
The default scrape interval is 60 seconds, but it can
be extended via a configuration option.

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.

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.
