Config management class

Configuration management package

• Yaml based
• Can use a config template embeded in your application distribution, and a local config (in /home/var/{application}) customized for your particular installation (that could be edited manually, or by your ansible recipe).
• Local config will be merged with the template in your application overwritting its values, allowing you to upgrade and distribute your application adding new fields with default values seamlessly.
• When merging two lists, if the items inside are dicts it will identify them as equal if the field 'name' matches.
• Provides functionality not only to read the configuration, but also to modify it in runtime
