wait_for module waits 300 seconds for the port started or stopped.  This

When Kibana interface is opened for the first time, it requires creating
a default index pattern. To view, analyse and search logs, at least one
index pattern has to be created.
This patch automate "flog-*" default index pattern creation and set it
has default config.

This patch includes changes relative to integrating Heka with
Elasticsearch and Kibana.

The main change is the addition of an Heka ElasticSearchOutput plugin
to make Heka send the logs it collects to Elasticsearch.

Since Logstash is not used the enable_elk deploy variable is renamed
to enable_central_logging.

If enable_central_logging is false then Elasticsearch and Kibana are
not started, and Heka won't attempt to send logs to Elasticsearch.

By default enable_central_logging is set to false. If
enable_central_logging is set to true after deployment then the Heka
container needs to be recreated (for Heka to get the new
configuration).

The Kibana configuration used property names that are deprecated in
Kibana 4.2. This is changed to use non-deprecated property names.

Previously logs read from files and from Syslog had a different Type
in Heka. This is changed to always use "log" for the Type. In this
way just one index instead of two is used in Elasticsearch, making
things easier to the user on the visualization side.

The HAProxy configuration is changed to add entries for Kibana.
Kibana server is now accessible via the internal VIP, and also via
the external VIP if there's one configured.

The HAProxy configuration is changed to add an entry for
Elasticsearch. So Elasticsearch is now accessible via the internal
VIP. Heka uses that channel for communicating with Elasticsearch.

Note that currently the Heka logs include "Plugin
elasticsearch_output" errors when Heka starts. This occurs when Heka
starts processing logs while Elasticsearch is not yet started. These
are transient errors that go away when Elasticsearch is ready. And
with buffering enabled on the ElasticSearchOuput plugin logs will be
buffered and then retransmitted when Elasticsearch is ready.

Due to poor planning on our variable names we have a situation where
we have "internal_address" which must be a VIP, but "external_address"
which should be a DNS name. Now with two vips "external_vip_address"
is a new variable.

This corrects that issue by deprecating kolla_internal_address and
replacing it with 4 nicely named variables.

kolla_internal_vip_address
kolla_internal_fqdn
kolla_external_vip_address
kolla_external_fqdn

The default behaviour will remain the same, and the way the variable
inheritance is setup the kolla_internal_address variable can still be
set in globals.yml and propogate out to these 4 new variables like it
normally would, but all reference to kolla_internal_address has been
completely removed.

To allow for TLS to protect the service endpoints, the protocol
in the URLs for the endpoints will be either http or https.

This patch removes the hardcoded values of http and replaces them
with variables that can be adjusted accordingly in future patches.
