Single quotes around variable, meant that it was checking for a package literally called '$::redis::package_name', rather than the actual package_name, passed to the redis class.

* Move pidfile settings from global section as a name of pidfile on FreeBSD platform is different
* Move workdir settings from global section as a database on FreeBSD platform placed on different place

* Mainly from voxpupuli’s module sync
* Simplified Travis Matrix
* Updated Rakefile with options

FreeBSD fixes

Consolidate travis and testing

Add save interval squash

Redis 3.2 introduced 'protected-mode' to enhance security. The feature introduces an error in the sentinels when trying to connect from non loopback interface :

```
DENIED Redis is running in protected mode because protected mode is enabled, no bind address was specified, no authentication password is requested to clients....
```

Fix adds 'bind' to the sentinel template in order to allow the sentinels to communicate.

class { 'redis::sentinel':
  sentinel_bind => '0.0.0.0',
}
```

* Update apt module for new changes

* Pin Beaker version

Fix Beaker settings

Add fast finish to Travis

Sent bind address rebase

* No longer need to re-scope them to the config class
* Use scope lookup for variables
* https://docs.puppet.com/puppet/latest/reference/lang_template_erb.html#scopevariable-or-scopelookupvarvariable

Remove single quotes around variable

* Right now package is checked with a defined function
* If user doesn’t want to manage the package or is managing somewhere else, they should use the parameter not to manage it

* Also add Beaker docker jobs for acceptance testing Redis more now we’ve slimmed down the unit tests

Speed up Travis even more

* powerstack.org no longer exists
* Redis is now in EPEL

Closes #103

* Fixes failing beaker test
* Add spec for new setting for Debian

adding /var/run/redis for Debian based hosts

Changes package installation

Changes templates to use scope

* Will be useful in the future to only allow 3.3+ config on newer packages
* Also useful for seeing the version of the redis package easily

define sentinel process status independently
