Combined the lamp_simple_rhel7 and wordpress-nginx creating wordpress-nginx_rhel7 

Added support for rhel7 for the Wordpress Ansible playbook. Since its
not backwards compatible I have placed it in a new folder. Also updated
it to the newest version of Wordpress

Need add Start Of the Services on Reboot: Start nginx + php-fpm services

Updated Wordpress version and made it to start on boot

Added RHEL7/CentOS 7 compatible version of lamp_simple

RHEL7 version reflects changes in Red Hat Enterprise Linux and CentOS
7:
1. Network device naming scheme has changed
2. iptables is replaced
with firewalld
3. MySQL is replaced with MariaDB

Rewritten for mysqli

Changing root MySQL user is not a good idea, it is better to add our own
user instead.

mysql PHP extension is deprecated, rewritten for mysqli

Fixes compatibility with Consistent Network Device Naming scheme

Fixes compatibility with CentOS and other OSes that use Consistent
Network Device Naming.

Proof MongoDB readme

Update HAProxy rolling_update.yml example - use haproxy module.

Remove trailing space

hardcore nitpicking as I follow along <3 thanks for all your hard work!

Move update defines above wp-settings include

Add alternative example for string finding

Another way in which the output of command can be matched against a string.

fix MongoDB example

No deletion/creation of tomcat home.

The user module doesn't have to create it with this option.

Fix variable interpolation syntax

Add examples for `stdout` loops

These 2 methods are mentioned [here](https://docs.ansible.com/playbooks_conditionals.html), so I thought it'd make sense to have them in the repo too.

Updating WP to latest version

Switch to Tomcat 7.0.61 and use archive.apache.org instead.
