This is a Logstash component which reads processed logs from Kafka
and writes them to Elasticsearch (or some other backend supported by
Logstash).

Ingesting the logs from this service with Fluentd will be covered under
a different commit.

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

There are cases when we can lost original timestamp field given from
logs, like when we send our logs to the next fluentd forwarder in chain
of forwarders, it will rewrite our timestamp by default. Save
`Timestamp` field explicitly to avoid such situation and be able to
reconstruct messages date and time.

Use Zuul's filtering mechanisms to only run the bifrost CI job in the
check pipeline when changes are made to the bifrost role. This should
reduce load on the CI system.

Also adds a periodic pipeline containing the bifrost job.

In I86bf5e1df3d6568c4f1ca6f4757f08a3dd22754d, creation of the kolla user
was moved to after package installation to ensure the sudo package is
installed when required. This change does not work when python
dependencies are installed in a virtual environment however - when the
virtualenv variable is set.

This change moves the ownership change of the virtualenv to after the
kolla user has been created. It also uses the kolla_user and kolla_group
variables to set the user and group appropriately.

The Monasca Log Transformer takes raw, unstandardised logs from one
Kafka topic, standardises them with whatever rules the operator wants
to use, and then writes them to a standardised logs topic in Kafka. It
is currently implemented as a Logstash config file.

Since Kolla does a fairly good job of standardising logs, this service
does very little processing. However, when other sources of logs
are used, it may be useful to add rules to the Transformer, particularly
if it's not possible to standardise the logs at source.

Ingesting the logs from this service with Fluentd will be covered under
a different commit.

this change uses the same format for Kafka.
