Haproxy

These are the changes that I have made as a solution to issue #67 (closed). There are some major changes in here that I have tested in a test environment and worked so I hope that it doesn't shut down HAproxy.

1. apps/haproxy/configure-haproxy.sls

• I changed the jinja to use hostnames instead of IP addresses from HAproxy routing. the data is pulled from a new file that I created in pillar.

2. /haproxy.cfg

• I changed the names to reflect the variables in configure-haproxy.sls

3. /configuration.sls

• This is the haproxy configuration file made into a template and stored in pillar. There is a lot more information in this configuration that can be used to better automate HAproxy. I have started in the automation but I wanted to make sure that these changes work first then I will add a haproxy.jinja template that populates from this pillar data.

4. /hostnames.sls

• This file contains the data that populates the /etc/hosts file on all salt-minions to enable networking by hostname instead of IP.

5. /defaults.yaml

• This file contains the default IP data for the /etc/hosts file on the salt-minons

6. /hosts.sls

• This file was changed to add the hostnames of all the salt-minions to the /etc/hosts file of a salt-minion to enable routing by hostname.
