Parsing of files in configuration directory

[duebbert]

It would be very useful, if Config.__load_config_file() also checked for a directory with configuration files and load them. Example:

/etc/mysoftware>/config.conf   <-- Main configuration file
/etc/mysoftware>/config.conf.d    <-- Directory with additional configuration files extending/overriding the main configuration file
/etc/mysoftware/config.conf.d/01_some_file.conf   <-- File with additional configuration options.
/etc/mysoftware/config.conf.d/02_and_some_more.conf

The reason this would be very useful is that in a distributed environment managed with chef/salt/ansible/whatever, I could have the same base configuration file that gets installed on every server but then distribute individual files which enable certain functionality to some machines.

I would use this with the newrelic_plugin_agent to enable different plugins on different machines.

I don't think this would be difficult to implement. If I can find the time I can look into it and send a pull request but maybe someone else could do it faster.
