Release for PuppetForge

This is released at https://forge.puppetlabs.com/dwerder/graphite

Features:

• Nginx/Gunicorn is now fully supported on both Debian and RedHat-like systems
• The correct username/group is now used across apache/nginx for both Debian and RedHat
• Pip is now the default provider for Django to ensure mutually-working package versions are installed.
• Added systemd scripts for when $service_provider == 'systemd'
• Added workaround for race condition bug in graphite
• Added configuration variable gr_web_server_remove_default -- default config is only wiped when the variable is true, or when it is undef and gr_web_server_port == 80
• Renamed gr_apache_port and gr_apache_port_https to gr_web_server_port and gr_web_server_port respectively. If the old configuration values are used, puppet fails telling you to use the new ones.

• Add support for custom directory locations , see gr_base_dir and gr_*_dir
• Add gr_relay_diverse_replicas option, default to true
